1. High efficiency of wear material, wear evenly, the lifetime of the Coarse Powder Mill is three times higher than that of Raymond Mill;
2. High percentage of sand can be produced by the Coarse Powder Mill;
3. The Coarse Powder Mill are highly efficient desulfurization equipments of power plant. The Coarse Powder Mill can grind CaCO3 into fine powder less than 1-2mm, the desulfurization effect is better;
4. The Coarse Powder Mill can be used as pre-grind equipment before ball mills; the ball mills efficiency will increase 50%;
5. Products out of the Coarse Powder Mill can be used to make firebrick, concrete brick, block and other new building materials;
6. Mainly used for pre-processing of various crushable non-inflammable & non-explosive brittle material with Mohs Hardness less than nine.
