Features of silica sand rod mill: Feed particle size: ≤50 mm Discharge particle size: 0.833-0.147 mm Used for grinding silica sand to achieve the required particle size, with a processing capacity of 0.62-180 t/h. The particle size of the ground silica sand product is relatively uniform, and the phenomenon of over-grinding is less.
