Based on our experts years research experience in the milling industry and considering recommendations and requirements of domestic and foreign clients. It is the ideal equipment to replace Raymond Mill, ball mill, and other traditional mill which only process fine powder materials. It is high-efficiency equipment and widely applied in quartz sand, silica sand, foundry sand, fine sand and other sand abrasive industry. By being a component of closed production lines, it can produce various size products of better effect.

 Technology Advantages
1. High efficiency of wear material, wear evenly, the lifetime is three times higher than that of Raymond Mill
2. High percentage of sand can be produced by this machine
3. The mill is a highly efficient desulfurization equipment of power plant. It can grind marble into fine powder less than 1-2mm, the desulfurization effect is better
4. This machine can be used as pre-grind equipment before ball mill; The ball mill efficiency will increase 50%
5. Products out of this machine 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.
