Concrete shot blasting machine

Operation

Concrete blocks, slabs or stairs are placed on the inlet side of the conveyor belt using handling equipment. When released by the machine operator, the conveyor belt advances one batch at a preset transport speed, exposing the concrete pieces in the blasting unit to the abrasive stream.

After blasting, a high-pressure blower with a height-adjustable nozzle removes any remaining abrasive from the workpiece. The use of handling equipment during the loading and unloading process ensures a flexible manufacturing process and a high material yield.

The inlet and outlet passages are sealed with wear-resistant rubber curtains. After passing through the shot blasting unit, the finished parts reach the outlet area, where they are removed from the conveyor belt.

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

Concrete shot blasting machines are used for surface finishing of concrete blocks, concrete slabs, concrete stairs and similar concrete products. Exposure to the abrasive blast brings out the mineral components of the concrete and gives the surface a special appearance.
