Rubber belt shot blasting machine

Operation

The loading device loads the workpieces directly into the shot blasting machine from containers, pallets or so-called loading baskets. The workpieces slide through the open loading door and onto the tread of the advancing caterpillar track.

The loader then returns to its initial position. The blasting process begins after the loading door is automatically closed and locked. Once the blasting period is complete, the door opens automatically. The freshly blasted parts are removed in sequence by means of an outfeed conveyor or by emptying them directly into containers provided by the customer.

The abrasive is continuously cleaned, recirculated and reused. An abrasive dosing device feeds the clean abrasive from the abrasive storage tank to the high-performance turbines.

A fan creates the partial vacuum necessary to maintain dust-free operation of the blasting unit. The extracted air is cleaned in a special filter unit.

Capabilities and applications

The shot blasting machine design has been recognized for decades as the most effective shot blasting process for removing scale, rust and burrs from mass production parts requiring the rubber mill design found on our MG model shot blasting machines. The shot blasting machine's endless rubber mill continuously tumbles the parts and exposes them to the abrasive stream throughout the shot blasting time. The use of a rubber mill ensures a relatively gentle tumbling motion. Since clearances are kept small, it is also possible to shot blast extremely small parts.

Machines of this type can be filled and emptied in a variety of ways. For example, with an automated loading device and conveyor belt, with manual loading and unloading in semi-automatic mode, with lifting equipment or with direct unloading into containers provided by the customer.
