TB-3 Tumble Barrel

TB-3 Tumble Barrel
Choose the type of abrasive delivery (wet or dry) choose the abrasive and cabinet size and add the cost of the TB-3 option to the model cost for total machine cost. Barrel capacity is a function of total part weight or total part volume and all parts are not equal. Most full loads are just below the barrel loading entrance hole or about 1/3 volume unless the maximum

Most applications today using directional blasting cabinets require hand-held guns for part processing but there are some parts that process better and faster using batch loads. This is the function of all tumble basket and tumble barrel models.

All Media Blast Tumble Barrels are listed as machine options. While the option can't be purchased without purchase of a machine model, this does allow the option to be added to any machine model, wet or dry, with and without pneumatic conveyor, for standard to ultra-fine abrasive.

The TB-3 is a full production Tumble Barrel Option with a square cabinet design and no manual blasting station. It uses the largest barrel size, 22" diameter, and operates using up to 50 cfm to eliminate part damage. Because it's a barrel and not a basket it has the fastest random part mixing for the fastest possible cycle time only requiring a single gun. The TB-3 uses a variable speed drive, a 1-1/2" diameter support shaft and a 22" diameter barrels for up to 50-pound part loading. This unit normally has a cycle time of 20 minutes for load of such size. This model is commonly used to remove heat-treating scale, prepare and clean parts for centerless grinding application or surface finish parts in batch loads before assembly.

The TB-3 has the largest attached dust collector, 440 sq.ft. of cartridge filer dust collector and automatic timed dust collector cleaning cycle, but can also be purchased less dust collector for operation on the 4-cartridge 880 sq.ft. automatic timed reverse pulse cleaning optional dust collector or any existing central dust collector.

Technical Information: TB-3 Option
Option Tumble Barrel (can be added to any industrial mode, wet or dry)
Compressed Air Usage TB-3 Option: 56 cfm @ 100 psi (most tumble machines operate at higher pressure because of the distance of the nozzle to the parts)
Suggested Air Compressor:

TB-3 operation requires compressed air in addition to the air usage required by the machine it’s being added to. Check line pressure making sure it's 100 psi or higher for proper operation of any TB model. Distance from the nozzle to the part requires higher than maximum impact velocity blasting pressure, and while lower pressure will work, the loss of frictional heat can increase processing time.
Air compressors vary greatly, check the cfm output on the compressor being used or visit Air Basics for more information on compressor selection.
Pro Tip: Never buy a compressor using the displacement cfm number, always use the second cfm volume number listed with 90-100 psi inside the tank, because tank pressure reduces performance.

Recommended Abrasive Size: 60 to 150 mesh for internal separator reclaimer, 80 to 240 mesh for pneumatic conveyor operated machine or external separator reclaimer
Most Used Abrasive Type Glass Beads, Aluminum Oxide and Silicon Carbide. (Due to distance-to-parts the processing pressure may be higher than maximum impact velocity.)
WARNING: Abrasive Restrictions and Warning
Paint Specification: Environmentally friendly, high-grade polyurethane high gloss paint. Standard colors include MBA beige and high gloss light gray. Custom color matching is available using customer supplied color sample, please call 866-204-7068 for pricing.
