Machines have a perpetual caterpillar made from perforated rubber belt. Treated objects are put by a special filling contraction to the caterpillar. When caterpillar moves its special shape causes treated objects to turn and roll, which causes the whole surface of the treated object to be quality blasted in a jet of abrasive. For emptying, the caterpillar is started-up in the opposite direction turning mode.
The machine's housing is protected by wear-resistant manganese steel. High efficiency of the machine is provided by the system for continued returning and cleaning of the abrasive, along with efficient turbines made from wear-resistant materials.Standard equipment of larger machines includes PLC Siemens, display, timer automatic or manual mode, automatic start-up of turbines, working-hours counter, etc.The machine may be equipped with a magnetic separator, vibration conveyor and variable frequency drive for the turbines.
