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 Barrel Models are listed as machine options. Why? While the option can't be purchased without purchase of a Media Blast® sandblasting cabinet, this does allow the tumble barrel options to be added to any machine model, wet or dry, with and without pneumatic conveyor for course to fine abrasives sizes.
Barrel capacity is a function of total part weight and or total part volume, and not all parts are equal. Most full loads are just below the barrel loading entrance hole or about 1/4 to 1/3 volume unless the maximum weight capacity has been exceeded. Barrels are like tires on car with a big balloon tire and small wheel size. The wheel, or hubcap, is where you have the gun placed that blasts into the rotating barrel.
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 operator blasting station and a 48” wide cabinet. The smaller barrel size allows the operator to process small batch sizes on parts too small to hold or just too many to manually blast. The TB-1 option includes the second abrasive delivery gun with solenoid operated gun, jog barrel control, and additional machine side access door and the controls for the gear motor drive motor assembly complete with mechanical timer and safety door interlock. There is a lot to having a tumble barrel or basket on a blast cabinet. 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.
While this may seem to be odd, having an option listed, all additional features required to make the tumble barrel complete are included in the cost of the option. Some require upgrades to the standard machine model, and are also included in the optional features. Adding theoptions to the machine model eliminate having 50 different tumble barrel machines.

NOTE: Standard Features are included with every model. Available Options can be added at additional cost and may require custom machine work, which may increase machine delivery time.
A barrel option – added to any 48″ wide machine model (can be added to any industrial model, wet or dry)
Wet or Dry, siphon or direct pressure
25 cfm barrel gun, 2nd manual blast gun is larger
25 cfm @ 100 psi
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.
0-150 mesh internal separator
Varies with machine model, 60 to 150 mesh for internal separator reclaimer, 80 to 240 mesh for pneumatic conveyor operated machines or external cyclone separator reclaimer
Glass Beads, Aluminum Oxide and Silicon Carbide. (Due to distance-to-parts the processing pressure may be higher than maximum impact velocity.)
TB-1 optional can be added to almost any new Media Blast® model, wet or dry
Variable speed 6 rpm max, adjust for barrel size – 12-16” barrel diameter –1″ diameter barrel jack shaft and bearings – includes 2nd access door and 2nd abrasive mixing valve on all dry models
