6. Working Principle of RSH 3.10 Shot Blasting Machine

Hanger Type Shot Blasting machine works on the principle of centrifugal. The products to be cleaned are hung on a rack located in the center of the spray chamber. This mount will be driven around by a separate electric motor. The ball heads are centrifugal nozzles. In the psychological firing head, there are ball propellers, ball guide cups, and ball feed cups. The balls will be shot out by the head at a very high speed (about 80mm/s), giving the balls a very large kinetic energy. This kinetic energy will clean the surface of the product to be cleaned.

The balls after being shot into the cleaning product will fall to the bottom and be recovered by the ball collection system through the dust filter system from the balls, and the clean balls are returned to the ball container on the machine. This ball storage tank will continue to supply balls to the ball heads. This process is continuously cyclic throughout the shooting process. During the blasting process, dust will be generated and this amount of dust will be collected by the dust collector and filtered to retain dust in the dust filter, avoiding dust generation into the environment.

After 1 cleaning cycle, the operator will open the door to take out the cleaned product. At the same time, continue to feed the uncleaned product to the mount for a new firing cycle.
