Secondly, scraper plate is driven to rotate by the driving system, then the shots and sand are transported to the lower of the elevator and elevated to the separator by the elevator for separation. The intact shots go through the shot feeding pipeline and gate for continuous use of blast wheel. The broken shots get into other pipelines for secondary separation.

The friction wheels on the driving mechanism of rotary table shot blasting machine is driven by a cycloidal-pin wheel reducer and is friction driven with the rotary table through a clutch mechanism, enabling the rotary table to rotate smoothly. When the workpiece rotates out of the chamber, the workpieces can be turned over and adjusted directly; the clutch handle can be pulled according to the difference of cleaned workpieces and the complexity of loading, unloading and overturn of workpieces, making the friction wheel be detached from the rotary table, namely the handle position is changed after the rotary table is stopped and adjusted, then the rotary table begins to rotate.
