[0025] In a preferred embodiment, there are two screw rods 10 , and the two screw rods 10 are respectively arranged on both sides of the inner cavity of the processing chamber 1 .

[0026] By arranging two screws 10 on both sides of the inner cavity of the processing chamber 1, when the height of the grinding equipment 15 needs to be adjusted, it is only necessary to drive the screw 10 to rotate under the action of the lifting motor 9, so that the outer wall of the screw 10 drives the lifting plate 11 to move downward along the outer wall of the screw 10 during the rotation process, thereby realizing the adjustment of the height of the lifting plate 11.
