Shot blasting machine for steel mills

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 tumble blast principle has been recognized for decades as the most effective blasting process for removing sand, scale and burrs from heavy or sharp-edged mass production parts requiring the rugged steelwork design found in our MR Model tumble blast machines. Mounting screws attach the machine's steel plates to the track links. These links are then joined together with appropriate connecting hardware. The tumbling motion of the mill ensures that the work pieces are exposed to the abrasive blast throughout the blasting period.

Machines of this type can be filled and emptied in several ways: with an automated loading device and extraction belt, or with other equipment already integrated into the rest of the production line.
