100% Welded: Often times, less expensive blast machines are manufactured using light gauge steel with spot welded cabinet construction that can lead to shorter cabinet life and abrasive leakage when the machine is being used. Every machine in the Media Blast product line, including, all of our light duty models, are 100% welded utilizing 12 and 14 gauge steel for the construction of the machines. This gives you a more durable machine construction and prevents cabinet leakage during machine operation.
Abrasive Gun Oscillators: The feasible number of guns used in one cabinet is determined by the abrasive type and the part shape. Too many guns will create very high machine maintenance and operating cost. Gun oscillators are used to cover a wide area but, keep in mind, gun overlap is required, and this overlap reduces conveyor speed. Many different types of oscillators are used with special machines.
Abrasive Hopper Tuner Valve: All machines that include the pneumatic conveyor include an outside abrasive storage hopper. Because the pneumatic conveyor must handle all the abrasive each time it exits the blast nozzle, it must be nearly 100% efficient. This can often retain dust that can affect cabinet visibility. The tuner valve is set by the customer to eliminate unwanted fine dust during abrasive conveyor operation. Elimination of the finer dust will help with cabinet visibility.
Abrasive Mixing Valve: The abrasive mixing valve is used to meter and control the amount of abrasive entering the abrasive delivery hose. A properly adjusted abrasive mixing valve helps to eliminate all abrasive delivery surges and it also allows for re-adjustment of flow when changing abrasive sizes. Blasting machines are not capable of the fine adjustment required, for the wide variety of abrasive sizes available in the industry today unless, they have a quality mixing valve.
Abrasive Separator: See Separator Reclaimer
Ambient Air Dryer: Moisture in the compressed air supply causes abrasive flow problems and dust collector filter problems. MBA's unique inline ambient air dryer requires no floor space and mounts directly onto the blast cabinet.
Bar Grating: Grating material is used in large abrasive blasting cabinets because of its strength when spanning great distances without additional support. It is also used when high wear abrasive applications exist.
Barrel Reclaim Separator: This option is available with the pneumatic abrasive conveyor in lieu of the high efficiency cyclone separator reclaimer that is used with the finer abrasives. It is used for applications that require conveying the abrasive outside the blast cabinet when the abrasive size is large, 60-120 mesh. This option will increase the life of the separator when used with larger cutting abrasives.
Batch Loads: Is a term used to describe small parts processing without operator contact. Batch loads are processed using a rotating basket or barrel assembly. As the barrel or basket spins, random part mixing takes place inside the barrel or basket, this, coupled with a fixed gun directional blast pattern, processes parts in a given time period without the need for a machine operator.
Belt Conveyors: Parts can be passed through cabinets using many different belt types, link belts and flat belts being the most common. Multiple gun stations are used, both fixed and oscillating, to cover the part moving on the belt assembly.
Blow-Down Controls: The Blow-Down Controls option allows for the quick depressurization of the blasting pressure pot, which permits faster pot re-fill. The smaller the blasting pot, the more beneficial the blow-down controls are.
Blow-Off Gun Assembly: All production cabinets manufactured by Media Blast include the inside cabinet blow-off gun assembly. This feature is also available as an option on the Light Duty and General Purpose blasting cabinets.
Boron Carbide: Is a high wear material that is used for blast nozzles when a cutting abrasive is used. Boron Carbide is about double the cost of the less expensive tungsten carbide but, it will last 4-6 times longer in use.
Cartridge Filter: Unlike other filtering materials used for dust collector, 'cloth', the filter cartridge has a certified nearly HEPA quality to it. Cloth filters consist of woven materials that stretch during the cleaning process resulting in reduced filter efficiency. Filter cartridges also yield greater filter collection surface in a smaller required filter area. When purchasing a machine, filter replacement time and cost, is greatly reduced when using cartridge style filters.
Certified HEPA After Filtration Packages: HEPA After Filtration is not always used for hazardous dust. This option can be used for Cell machines, Small Room machine operation or Ultra-Fine abrasive applications to control legal grains per cubic meter on dry abrasive blasting equipment. Also offered for applications dealing with hazardous dust conditions.
Clearview Window: Oversized operator's view window.
Contained Dust Discharge Assembly: MBA expands upon its popular hopper style dust collector by offering a contained dust discharge assembly (standard with HEPA filtration). This assembly incorporates a slide gate on the bottom of the dust collector hopper. When the slide gate is opened, the dust is released through a duct and into a dust collection vessel. When the dust collection vessel is lined with a bag, the vessel top can be removed and the contents disposed of without the operator ever being exposed to the dust. This option is highly recommended for operations blasting with hazardous abrasives or blasting on materials that may release hazardous material dust. Slide gates and taller hopper heights are available to accommodate drum waste disposal. Dust collection systems are also available to accommodate the use of a full size steel drum.
Cutting Abrasive Package: This should be included on machines operating with high wear or cutting abrasives. The package consists of a window protector, boron carbide nozzle, white polyethylene cabinet wear plates, heavy-duty bar style work grates and a steel hopper wear plate. Certain MBA machine models include some of these items as standard features.
Cyclone: Is a pneumatic centrifuge used to separate and retain abrasive sizes that are 150 mesh and smaller. Cyclone Separators also introduce air into the abrasive which helps to keep the abrasive dry. This creates a more uniform delivery of the finer size abrasives.
Direct Pressure: Direct Pressure machines use a pressure vessel to pneumatically push the blast media through a single abrasive hose and out the blast nozzle. Direct Pressure machines can be used with heavy abrasives like steel shot or steel grit, in addition to most other common abrasive types and sizes.
Is a term used to describe abrasive blast machinery equipped with handheld or fixture mounted blast guns. This allows for specific part areas to be processed and prevents the blasting of areas on the part that you do not want processed. Operation of the blasting is accomplished by using compressed air to convey the abrasive media through the gun or guns to the part surface.
Double Skinned, No Spill Door with Heavy Duty Appliance Style Latch: MBA uses a heavy duty latch mounted to a double wall, 14 gauge steel door. Our doors will not warp or flex and our cabinets do not leak abrasive when the doors are opened.
Downdraft: Is a term used to describe the direction and speed of air flow. Downdraft is frequently used to describe the speed of air, just above the work surface, of a pollution control workbench.
Enclosed Top: All Tornado models are available with an optional Enclosed Top Assembly upgrade, which is used to help confine dust particles with increased dust particle velocity. This top assembly includes the back, sides, top and movable operator view panel. The standard panel is constructed using a hinged Plexiglas panel and an operator open work port area is located below the operator sight panel. This panel is also available in optional safety-glass construction to eliminate possible scratching. The Enclosed Top is used to confine dust particles being accelerated during sanding, de-burring and many other operations.
Ergonomic Sit Down System: This option is available as a bolt-on padded shelf style armrest that attaches to the complete line of Micro Blast Machines. It is also available as a system that can be incorporated into a complete custom blast cabinet. This custom option includes a different window slope that has been lowered to improve visibility into the blast cabinet from the sit down position. The blast cabinet hopper has been redesigned so that the operator can sit comfortably while blasting. An adjustable armrest and shrouded foot pedal completes the package.
Ergonomically Constructed Cabinets: Ergo can be more than just sitting down. Cleaning the dust collector, setting the controls and movable foot controls are also part of properly designed cabinets. Ask Media Blast about all the features that create a True Ergo machine.
In Blasting Cabinets:
The machine exhaust blower is used to create cabinet visibility. It is a necessary
component for the efficient operation of abrasive separator reclaimers. Separator
reclaimers remove unwanted dust and spent abrasive from inside the cabinet. To
establish the number of cabinet air changes per minute made possible by the exhaust
blower, take the cabinet blast chamber area in cubic feet and divide it into
the exhaust blower CFM rating. Exclude the machine hopper size when calculating
the cabinet volume.
In Tornado Pollution Control Benches:
Important to any down-draft work bench, is the type of blower being used. The
exhaust blower creates the down-draft air-flow used to capture the dust and
contamination and the blower construction type, determines the suction rating
measured in Static Pressure, a measurement of inches of water lift. A
critical balance is needed between suction and air volume, and Media Blast
manufactures all of its blowers based on these two very important factors.
Exhaust Silencer: The Exhaust Silencer is used to reduce the noise level that is created by all Class III dust collector exhaust blowers. Larger blowers are used to create better cabinet visibility but, they also create noise levels that are unacceptable for continuous machine operation.
Expanded Cabinet Heights: MBA offers two cabinet heights on the most popular cabinet sizes (3636, 4836). Our standard height production blast cabinet has a 30" working height and a view window angle of 45°. This allows for the ergonomic blasting of smaller parts without having to put your nose against the view window while working. Our expanded height cabinet offers 36" of working height with a view window angle of 17°. This window angle is more efficient for taller parts that won't fit in the standard height cabinet. If the normal cabinet heights will not suffice, MBA offers extended heights as optional choices.
Expanded Two Cartridge Dust Collector Upgrade: This option provides more filter surface area (440 sq. ft.) when dusty abrasives are used or when the cabinet usage is three + hours per day.
Filter Cycle Cleaning Gauge: This feature is standard on all MBA production cabinets. This option is not offered at all on other manufacturers cabinets. Clean filters are an important part of the maintenance process. Neglect, will result in significant repair costs and lower productivity (due to poor visibility), so it is critical to know when to change the filters. The MBA filter cycle cleaning gauge helps to remind the operator when critical maintenance is due.
Fine or Ultra Fine Abrasive: Any material pneumatically propelled through a blast nozzle is commonly known as abrasive or blasting media. Fine and Ultra Fine abrasives measure 150-325 mesh in abrasive particle size.
Heavy or awkward parts can be moved much easier inside a blast cabinet when it is equipped with a turntable. The turntable can increase productivity significantly. Choose from manual or powered turntable models available in many sizes (up to 48" diameter) with a standard weight capacity of 300 pounds (heavier capacities are available). The frame to hold the turntable is mounted inside the machine and the turntable top rides and rotates 360 degrees on a series of double sealed bearings. All MBA turntables are slotted to allow for the use of part holding fixtures and they are equipped to lock in position if desired.
For turntables that exit the cabinet for loading and unloading see "Mobile Work Carts and Tracks".
Foot Operated Blast Valve: A foot operated blast control, gives the machine operator maximum mobility inside the blast cabinet, by controlling the blast cycle, using an on-off foot operated pedal. This is important when operating inside smaller cabinet sizes. This also creates a smaller, more compact, easy to use blast gun size. Trigger controlled guns are large and troublesome to operate when installed inside a blast cabinet.
Frictional Heat: Dry abrasive blasting generates surface heat on the part that is being processed. This frictional heat, can damage thin parts or parts made of certain materials such as plastics or composites. Frictional heat increases when the compressed air being used is increased and this is the single most important factor in reducing part-processing time when using larger gun sizes.
General Purpose: A term used to describe a "hybrid" mix of light duty and production machinery. The cabinet is large but, the dust collector capacity is limited. General Purpose or non-production machines are ideal for infrequent use on larger parts.
Glass Window Protector: Commonly called "Window Protectors", these are used to protect the operator view window during machine operation when using cutting abrasives. Cutting abrasives can cause window etch. MBA uses a secondary piece of glass to protect the main safety glass view window from being etched. The protector glass is replaceable and provides a durable, inexpensive, way to protect the view window during machine operation. Using softer materials like plastic sheets is not advised, due to the soft nature of the protector and its ability to create static electricity, which will draw the abrasive inside the cabinet to the view window, creating limited visibility.
Gun/Blast Nozzle Holding Fixture: This feature, allows the operator, to hold and maneuver the part to be blasted with both hands because, the blast nozzle is fixed in position. This option is recommended for operations that blast small or difficult to hold parts.
Hazardous Duty Dust Collectors:
Media Blast manufactures the Haz-Mat HEPA filtration package for reduced maintenance contact with collected dust. The standard dust collector requires that the operator come in contact with Primary Filters during filter replacement.
To minimize exposure to the collected dust that is generated in applications that may include hazardous materials, MBA has developed a hazardous materials dust collector. This dust collector package helps reduce operator contact with the primary filters during filter replacement. HEPA After-Filtration, Automatic Reverse Pulse Filter Cleaning and a direct reading monitoring system are included with this optional upgrade package making it right for collection of hazardous dust materials.
HD Kit: This model can be purchased without the HD Kit, the kit can be purchased and added at a later date. The Space Saver HD includes this HD Kit which produces 30 air changes per minute by using a separator reclaimer that removes the dust and dirt from the abrasive. If you are looking for 100% welded machine that you can operate using any Shop Vacuum, purchase the Space Saver HD without the HD Kit (the machine will include a smaller 12 CFM gun assembly to allow for operation with any Shop Vacuum Dust Collector).
HEPA is an acronym for High Efficiency Particulate Air Filter, which was used in U.S. military specifications beginning around World War II.
In Blast Cabinets:
This filter should be installed when hazardous materials are being blasted (e.g. chromium, cadmium, nickel, zinc, lead, asbestos, or radioactive materials).
In Tornado Pollution Control Benches:
The Tornado is a pollution control bench, used for collecting nuisance dust. The optional HEPA after-filter can be added, when better filtering ability is required for small room applications when greater dust capture is required. HEPA filters are not cleanable but, all Tornado units also include the standard primary filters that protect the HEPA filter during operation for better longevity.
High Velocity Part Vestibules: Passing a part through a blasting cabinet requires passing the part through a high-velocity vestibule with vestibule length to retain the abrasive inside the cabinet. This vestibule length with the cfm created by the dust collector blower is used to reverse abrasive direction and prevent abrasive escape. Unless this is calculated correctly the machine will not function properly.
High Wear Cabinet Kits: With any cutting abrasive some features are required to prevent excessive machine maintenance. Window Protectors, HD Bar Grating, Boron Nozzles and Liners are all items that greatly reduce operation costs. This can also lesson maintenance on non-cutting abrasives but, often are not included as standard.
Hopper Bottom Dust Collector: When looking for machinery, always look for a hopper bottom style dust collector for ease of cleaning. All Production style machines manufactured by Media Blast are equipped with dust collector dust storage hoppers. This allows for the removal of collected dust, into plastic storage bags, which prevents dust escape during machine service.
Hopper-Less Machine Construction: Media Blast offers air-swept floor sections to eliminate the height of standard machine construction using a hopper assembly. The width and depth of any cabinet with the angle of repose for the abrasive designs the hopper slope. Most operator work levels are 36-inches and higher. Hopper-Less construction lowers the work level to 18-inches. This can be useful for tall parts or parts passing through using an overhead hoist.
Integrated Vacuum Cleanup Assembly: MBA is the only manufacturer in the industry that offers this unique option. We convert the dust collector into a shop vacuum that can be used for cleaning up the work area around the cabinet and cleaning the abrasive out of the blast cabinet. This option requires a minimum of the dual cartridge dust collector and the 1,160 CFM exhaust blower.
Laminated Safety Glass: Two separate pieces of glass bonded together with a plastic sheet to prevent glass shards if the glass is broken.
Light Duty Blaster: Light duty, describes machinery used on a non-daily basis. One feature missing from light duty machinery is the production style dust collector with the large filter surface area. Light duty machines are the least costly to purchase and usually have cabinets measuring 24 inches by 24, 30 or 36 inches. These cabinets are generally manufactured using spot welded construction however, all Media Blast machines, are manufactured using 100% welded construction. Most light duty machines operate with no more than 20 CFM of compressed air.
Long Wear Abrasive Hose: A hose material used when high wear cutting abrasives are being used. This type of hose eliminates the frictional wear created on normal abrasive hoses.
Magnahelic Gauge: The magnahelic gauge monitors the condition of the dust collector filters (or HEPA filters) by monitoring the differential pressure between the clean and dirty side of the filter. The magnahelic gauge is available with or without set point indicators and indicator lights. When the filters become dirty, indicating the factory preset differential pressure has been reached, the set point indicator triggers a red light alerting you, that it's time to change the filters.
Magnetic Separator: This is used to remove metal contaminants that may be present during operation when using plastic abrasive.
Maintenance Meter or Hour Meter: This feature will simplify the maintenance on your new MBA blast cabinet by tracking the amount of time the machine is in operation. By using the non-resettable hour meter, you can create a logbook that indicates basic machine maintenance schedules, including abrasive change out.
Manual Reverse Pulse: This component is used to reverse the airflow direction inside the machines dust collector. This creates a quick pulse of air down the center of the dust collector cartridge which forces the collected dust off of the filter surface.
Micron: Unit of measurement, 25 microns equals .0012 or 1/25,000 of an inch.
Mirror Cabinets: Used to create the perfect fit with the smallest machine footprint. Any Media Blast units can be supplied in a mirror layout. Often used for left hand operation but, more often used to create a better shop layout and more efficient operation. Mirror machines include mirror service doors on the dust collector and often mirror blower rotation.
Mobile Work Cart and Track: For large, heavy and awkward objects that need to be blasted, the mobile work cart and track allow the objects to be easily loaded and unloaded from the cabinet. This eliminates the need for potentially dangerous clam-shell style cabinets. All mobile work carts are equipped standard with internal cabinet track and locking turntables with a 300 pound weight capacity. Various lengths of external track extensions and powered operation are also an available option.
MSDS: A material safety data sheet (MSDS) is a form containing data regarding the properties of a particular substance. An important component of product stewardship and workplace safety, it is intended to provide workers and emergency personnel with procedures for handling or working with that substance in a safe manner, and includes information such as physical data (melting point, boiling point, flash point, etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, and spill-handling procedures. MSDS formats can vary from source to source within a country depending on national requirements.
Multiple Gun Applications:
Multiple guns for siphon or multiple nozzles for pressure, with and without additional operator stations are available on most Production type equipment manufactured by Media Blast. Adding a Tumble Barrel to a standard cabinet also adds one more gun assembly with controls. This special feature has almost limitless possibilities.
ii. Oscillator Mounted
iii. Siphon or Direct Pressure
Multiple Work Stations: A 48" part inside a 48" cabinet will not move from side to side. Often part movement is required to process the ends of the part. With larger cabinets multiple operator work stations are often required for part coverage. Media Blast also offers a 90-degree operator work station on the machine side or side access door, this permits part processing from another direction without part removal and flipping of rotation.
OSHA Definition: Fibrogenic dust, such as free crystalline silica (FCS) or asbestos, is biologically toxic and, if retained in the lungs, can form scar tissue and impair the lungs ability to function properly.
Nuisance dust, or inert dust, can be defined as dust that contains less than 1% quartz. Because of its low content of silicates, nuisance dust has a long history of having little adverse effect on the lungs. Any reaction that may occur from nuisance dust is potentially reversible. However, excessive concentrations of nuisance dust in the workplace may reduce visibility (e.g., iron oxide), may cause unpleasant deposits in eyes, ears, and nasal passages (e.g., portland cement dust), and may cause injury to the skin or mucous membranes by chemical or mechanical action.
Open Top: All Tornado models include the Standard Top Assembly used to produce downward directional air-flow away from the operator location at the front of the unit. This top assembly includes the back and side wing pans used to create directional down-flow above the operator work grate surface increasing dust capture.
Pinch Roller Conveyor: Vertically mounted roller pairs used to push, pull or push-pull parts into and through a cabinet for processing. Horizontal pairs are used to rotate parts during processing.
PLC Machine Controls: Often used to increase production on parts moved into and out of or through the cabinet using various types of part movement or part conveyors.
A pneumatic conveyor is a device used to convey abrasive pneumatically during operation of the blast cabinet. Ducting is one of the more common products used for conveying abrasive.
The pneumatic conveyer works in conjunction with the cyclone separator for separation of fine and ultra-fine abrasive. Also used in operations with larger cabinets or multiple cabinets that requires standard operator heights.
Polyester Filter: This is a washable filter cartridge often used for applications that require faster cartridge cleaning.
Powered Mobile Work Carts: Mobile Work Carts roll into and out of the cabinet. All Media Blast Mobile Work Carts include a turntable assembly. This turntable can also be powered using a constant or variable speed gear-motor assembly.
Powered Roll-Up Doors: Vertical Doors can often save valuable floor space. Media Blast does not use counter-balanced or cylinder operated systems. Manufactured as a complete assembly in a steel housing mounted to the top of the cabinet. This option can be manually operated or equipped with a powered gear motor assembly.
Powered Turntables: Fixed Turntables located inside the cabinet are often powered allowing the operator to jog parts within reach for part processing. Powered Turntables can also be used with a fixtured abrasive gun for part processing or it can be manual or time-cycle operated with constant or variable speed.
Four basic blower types exist. The lower the blower class, the greater the blower CFM air movement but this also lowers the blowers ability to create suction.
Tornado Pollution Control Benches:
Media Blast manufactures a Class III blower for all Tornado models creating a high blower CFM air movement at greater static pressure ratings. This moves air longer through filters that are dust laden. Air quantity and length of air movement are balanced using this Class III blower type.
Pressure Pot: These are used with direct pressure blast machines to pneumatically push the abrasive through the blast nozzle. Pressure pots produce a faster abrasive velocity, the most concentrated abrasive patterns and they can operate using the heaviest of abrasives i.e. steel grit and steel shot.
Production: Production blasting machinery is machinery that is used on a daily basis. The defining factor in production machinery is the dust collector. Production machines require large amounts of dust collector filter surface area. The larger the dust collector filter surface area is, the greater it's capacity for storing collected dust and maintaining cabinet visibility during operation. Dust collectors with dust storage hoppers are easier to clean and therefore cleaner to operate. Production cabinets are typically made using heavier gauge steel with 100% welded construction. They also have the greatest variation of cabinet sizing.
QwikStrip Nozzle: A longer than normal nozzle that is used to maintain high abrasive impact velocity and dense abrasive particle concentration. Because of the extended length of these nozzles, they can be used on direct pressure machines only.
Raised Operator Platform: This is a platform used to raise the operator height, which allows for placement of the pressure pot, below the machine hopper. By doing this, you produce a better machine hopper slope, for feeding the pot. This eliminates the need for a pneumatic conveyor on a larger cabinet, which substantially increases the operating cost of the machine.
Random Part Mix: This describes the part mixing that takes place during the tumble blast process. By increasing the random part mix speed, you increase the tumble cycle time, which results in greater machine production output.
Replaceable Hopper: MBA has the only truly modular blast cabinet. If the hopper wears out after many years of use, it can simply be replaced because, it is not welded to the cabinet. If your blasting requirements change, MBA's production blast cabinets, can be converted from one style to another, simply by changing the hopper or adding additional accessories. For example, a production siphon cyclone cabinet can easily be converted to a pressure cyclone, a siphon or a pressure blast cabinet. While many manufacturers can convert between siphon cyclone and pressure cyclone, no other manufacturer can measure up to MBA's flexibility. MBA is the only manufacturer that offers an optional system, which allows the user, to automatically dispose of the abrasive after one cycle or operate the system as a normal abrasive blast system, which automatically recycles the abrasive.
Reverse Pulse Dust Collectors: A device used to clean the dust collector filter surface by using a pulse of compressed air. This type of setup is recommended for use with two or more filter cartridges and where high humidity conditions exist. It can be automatic or manual pulse.
Roll Up Side Access Doors: In years past, some side access doors were vertical lift doors. Today's technology allows for construction of the side access door as a contained roll-up door assembly. This makes possible, the addition of a powered gear motor assembly and a rubber inside door lining. Closing the door inside the machine hopper is an advantage when using this type of access door.
Roller Conveyors: Simple roller conveyor sections or power connected rollers can be used to move flat parts or other parts using totes. Roller conveyors are restricted by the length and shape of the part.
Roller Conveyors: Simple paired roller sections or power connected rollers can be used to rotate single parts inside the cabinet or move flat parts through any cabinet using part totes. Roller conveyor layouts can be restricted by the minimum length and shape of the part.
Rubber Dipped Baskets and Barrels: Tumble Basket and Barrel machines require the parts to be rotated inside the barrel assembly. The parts provide the required protection for the baskets and barrels during the blasting process. Often times, the steel basket or barrel requires rubber dipping to prevent the parts from being damaged when the parts rub against the steel barrel surface during the tumbling process.
Safety Door Interlocks: Standard on all production blast cabinets and optional on all light duty cabinet models. A safety door interlock, shuts off the air to the blast nozzle, when the door is open or if the door is opened while blasting is in progress.
Safety Plate View Window: Glass view windows perform best because, unlike Plexiglas or plastic which attracts abrasive dust via static electricity, glass is a more durable static free material. Safety plate glass is one of the safest materials because, unlike tempered glass, safety glass is comprised of two pieces of glass bonded together with a single clear plastic sheet between them.
Satellite Part Rotation: A Part Rotation Fixture used to spin the part in conjunction with fixed or oscillating abrasive guns. It can be stationary or attached to the powered turntable assemblies.
Scrubber: Wet type scrubbers are used for many applications for the collection and cleaning of both gas and solid dust particles. Any possible explosive dust will require wet scrubber collection to eliminate the fire hazard. Most are made using stainless steel construction with water and air-flow used for the collection of the dust.
Separator Reclaimer: The Separator Reclaimer or Abrasive Separator Reclaimer prevents the loss of usable abrasive when the exhaust blower exchanges inside air for outside cabinet air creating the negative cabinet air pressure. Abrasive separator reclaimers are pneumatic centrifuges capable of separating usable abrasive from dust and unwanted, worn abrasive. This device makes it possible for usable abrasive to circulate over and over inside the abrasive cabinet while removing unwanted dust which is a spent abrasive. Abrasive separator reclaimers are available in different efficiency ranges, which should be matched to the abrasive size in use. Some separators operate with media sizes of 0-150 mesh and others are intended for finer sizes of 180-400 mesh. In addition, separator reclaimers are available in different CFM ratings, with larger separators for larger exhaust blowers.
Shrouded Foot Pedal Assembly: An OSHA approved shrouded foot pedal assembly is available as an option to MBA's standard foot treadle. To accommodate the shrouded foot pedal assembly, the front leg brace is moved back 8" from the front of the cabinet.
Sight Window: Unlike the operator view window, the sight window is used to allow outside light to enter inside the cabinet. A Sight Window is often installed on the top of wet blasting machines to allow the light from the outside light fixtures to enter the cabinet.
Single Power Source: Machines with fractional motors operate from a 120-volt power source. Machines with increased motor horse power, 1 HP and larger are available with an electrical box, a transformer for low-voltage operator control, magnetic starter, heater and low-voltage fuse protection. This option, gives the customer the opportunity to choose the supply voltage and phase required for the application.
Siphon Blast: A term used to describe the type of abrasive delivery system used on an abrasive blasting cabinet. A siphon machine uses an injection gun to create suction on the abrasive supply hose. The abrasive hose then conveys the abrasive, using suction or siphon, to the gun where the compressed air hose is used to accelerate the abrasive. All siphon type machines include two hoses on the abrasive blast gun assembly. Siphon machines are the most common type of blast machine. All siphon gun assemblies include an air jet that is used to create the siphoning effect and also regulate the amount of compressed air required to operate the machine.
Soda: Soda or baking soda is a blast abrasive used for one shot applications where you dispose of the abrasive as soon as it comes off the parts that are being blasted. By doing this, you minimize contamination of the abrasive that could be transferred to the part. Soda is also used to prevent part damage on sensitive materials during the cleaning process.
Soda Delivery System: Optional Direct Pressure system used to deliver soda in the Blizzard model blast cabinet.
Special Blower Combinations: System Static Pressure can affects blower CFM. The amount of CFM introduced by the blasting nozzle(s) can require larger blower assemblies. Blowers are sized to the system static and machine requirements for operator visibility. This can often change the pneumatic conveyor by adding or changing the size.
Special Cabinet Layouts: Almost any customer required special cabinet layout can be supplied by Media Blast before the machine is fabricated. This is often required with many Oversized Parts, Special Operator Station Layouts, Part Entrance and Exit Vestibules, Taller, Wider, Deeper cabinets and many other simple modifications requiring cabinet modification before manufacturing.
Special Dust Collector Requirements: Media Blast offers Dust Collector Upgrades the include; HEPA After-Filtration, 2, 4 and 6 Filter Upgrades for 440, 880 and 1320 Sq.Ft. filter areas for high daily production and special blower configurations for high static and other increased blower cfm ratings required for additional dust collector options.
Special Electrical: Media Blast offers a full line of equipment operating on 120 volt, single phase power source. Some machines include High Voltage Single Power Source Electrical as standard. The customer can indicate any Voltage, Phase and Cycle to create a specific machine electrical package. All 120 volt models can be upgraded to High Voltage Single Power Source as an option.
Special Pneumatic Abrasive Conveyors: Siphon and Direct Pressure machines equipped with additional guns and or nozzles can often require larger abrasive storage hoppers and larger pressure pot assemblies. Media Blast offers non-standard pneumatic conveyors sized for non-standard blower cfm ratings and non-standard pressure pot sizes.
Stainless Steel Dry Cabinets: Media Blast is one of a limited number of manufactures offering stainless steel Wet Blasting Equipment. This allows Media Blast to also offer stainless steel dry cabinets required to lesson or eliminate carbon steel contamination during part processing. All cabinet items coming in contact with the abrasive are fabricated from stainless steel, including pneumatic conveyors and separator reclaimers. Some limited items, mixing valves etc., can be stainless construction by offered in standard mild steel construction standard.
Static Electricity Grounding Kit: Static electricity is generated when two dissimilar materials are rubbed together. This is a condition that can worsen with climate change. The static grounding kit prevents the cabinet from acting as a condenser, when the abrasive comes in contact with the steel cabinet walls, by preventing the static charge build up inside the cabinet.
Static Pressure can have many separate definitions determined by each application.
Tornado Pollution Control Benches:
With respect to the Tornado Pollution Control Work Benches, Static Pressure can be explained by saying the resistance of air to flow measure in Inches of Water. The higher the static pressure rating, the greater the suction ability of any blower or the ability to move air when resistance to air-flow is offered. This resistance is often called pressure differential, which takes the form of dust build-up on collection filters, creating a need for greater suction or static pressure ratings.
Steel Bar Grates: Media Blast uses two types of bar grate material, steel bar grating and fiberglass bar grating. Steel has a greater weight bearing capacity and fiberglass helps protect the parts from being scratched as they are being worked on.
Table Top Velocity: The down-draft velocity, movement of air in feet per minute, is greatest at the part work surface. Blower CFM divided by work surface area measured in sq. ft. equals table top velocity described in feet per minute velocity.
Timed Window Wash: This is a clear water rinsing assembly inside the cabinet that is timed, to provide a momentary pulse jet stream of clean water against the operator view window. All water used in this process is removed from the cabinet to prevent reduced slurry concentrations. The water that's removed from the cabinet can be used for cabinet make-up water.
Toe Kick: An open area at the bottom of a bench or cabinet, for the placement of the operator's feet, which allows the operator to stand against the bench or cabinet while working. Commonly used in kitchen cabinet construction.
Track Extensions: See Mobile Work Cart and Track
While most applications today using blast cabinets require manual operator directional blasting, some parts, because of their size and run quantity can be blasted in batch loads using a machine equipped with a rotation device known as a tumble barrel. The term Tumble Barrel, describes a horizontally mounted barrel with the rotation axis horizontal. Tumble barrel machines can process small parts up to 5 inches in length. Tumble barrel machines basically unload themselves because of the horizontal rotation axis of the barrel. This permits jog rotation of the barrel which brings the barrel door to the bottom, which allows the parts to drop into a container when the door is opened.
Tumble basket machines have an open top basket mounted with the rotation axis at 45 degrees from horizontal. These machines are used for the processing of smaller longer parts up to 7 inches. Because the tumble basket is mounted inside the machine hopper, the parts must be unloaded from the basket by hand after being processed.
Tumble Basket: See Tumble Barrel
Vacuum Blower: Vacuum Blowers are considered a Class four blower, used to flow limited air volumes at high suction ratings. They are used for high air suction velocities and limited air flow in small air ducts and or hoses. Not good for dust capture and collection because of the low air-flow amounts.
Wet Blaster: While most applications today require dry blasting, some remain that are truly jobs for wet blasting machinery. The frictional heat generated by dry machines can damage or destroy certain parts. Using a wet blasting cabinet can eliminate the frictional heat generated during part processing. Another plus with wet machinery is the ability to produce a chemically clean part surface with minimal surface removal. Using 4000 to 5000 mesh abrasive is not an option when using a dry blasting machine but, this abrasive size can be used when using a wet blasting cabinet like the Media Blast Hurricane model.
Window Molding Tool Kit: Media Blast uses a positive sealing window molding to produce a 100% sealed view window installation. Using the window molding tool kit allows for easy installation of the operator view window if replacement is ever required.
Window Protector Assembly: More commonly called "Window Protectors", these are used to protect the operator view window during machine operation when using cutting abrasives. Cutting abrasives are capable of creating window etch and using a sealed secondary window assembly located inside the machine will protect the more costly safety glass view window from being etched. Using softer materials like plastic sheets is not advisable due to the soft nature of this style protector and its ability to create static electricity, which will draw the abrasive to the view window creating limited visibility.
