If the raw material is granular silica sand, it can be directly entered into the classifying system after screening. Cassification After grinding, the sand slurry enters the hindered settling machine to separate the coarse sand to return to the rod mill for regrinding, and the overflow enters the hydraulic classifier to separate the fine sand.
