When the Stone mill/stone powder grinding mill is at work‚ the main bearing and each dial are driven by electromotor of main equipment through reducer‚ and all the grinding rollers are rolling in the ring channels driving by dial through plunger. The materials are driven to the edge of the turn plate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed‚ crushed and grinded by the rollers. Then the materials fall into multiple layers
