TB-1 Tumble Barrel

TB-1 Tumble Barrel
Barrel capacity is a function of total part weight or total part volume and not all parts are equal. Most full loads are just below the barrel loading entrance hole or about 1/3 volume unless the maximum weight capacity has been exceeded.

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-1 tumble barrel is a smaller variable speed barrel that is most often added to a manually operated machine that includes an offset manual blasting station. The smaller barrel size allows the operator to process small batch sizes on parts too small to hold. The TB-1 option includes the second abrasive delivery with solenoid operated gun, jog barrel control, and additional machine side access door and the controls for the variable speed drive motor assembly complete with timer and safety door interlock.

Choose the barrel size right for the part volume, 12, 14 or 16 inch diameter or order an extra different barrel size with the machine.

Technical Information: TB-1 Option
Option Tumble Barrel (can be added to any industrial mode, wet or dry)
Compressed Air Usage TB-1 Option: 25 cfm @ 100 psi (most tumble machines operate at higher pressure because of the distance of the nozzle to the parts)
Suggested Air Compressor: TB-1 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.
Note: The machine operates using the manual gun or TB-1 option separately, never both at the same time. The cfm usage of the machine is based on the manual gun size that may be larger than the optional TB-1 gun.
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 machines 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.
