The actuator is a belt - driven device, powered by an AC motor gearbox with variable speed control. The speed regulating knob is located on the control panel.

Suspended dust enters the dust collector through the pipeline on the side wall of the sandblasting room. Used abrasives are collected in the bottom silo and recycled back to the top through a bucket elevator to enter the pressure sandblasting circulation system.

The addition of abrasives is completed by pouring them into the sandblasting cabinet. When replenishing abrasives, the bucket elevator must be running. Add abrasives until the high - level abrasive indicator light comes on. This indicator light is located right below the cabinet door and is triggered by the paddle switch inside the level gauge.

The recycled abrasives are lifted from the sandblasting room by a 1.5kg bucket elevator. These abrasives are circulated to the vibrating separator, which removes abrasives and debris that are too small or too large in size. Reusable abrasives enter the pressure sandblasting system to supply the nozzles in the sandblasting room. The abrasive separator is a double layer 600mm device. Abrasives that are too large in size are discharged into the waste bin, and particles that are too small are sent to the dust collector. The coarse screen has 20 meshes, and the fine screen has 180/200 meshes. The degree of separation can be controlled by the adjustable vents on the side of the hopper to retain clean reusable abrasives and convey particles that are too small to the dust collector. Reusable abrasives enter the vibrating oversized debris screen from the cyclone separator to remove any large particles or debris. Then, the reusable abrasives fall into the hopper, ready to be used again.
