The machine has the characteristics of simple structure, reliable operation and convenient operation. It is by virtue of the principle that the size of solid particles is different, the specific gravity is different, and therefore the settlement rate in the liquid is different, the fine ore particles are floating in the water into overflow, and the coarse ore particles are sinking at the bottom of the tank. A grading device for mechanical classification by pushing the screw to the upper part of the discharge, which can grade the ground powder in the mill to filter, and then screw the coarse material into the feed port of the mill using the spiral plate, and discharge the filtered fine material from the overflow pipe.
