MSB Coarse Powder Mill is a kind of new high-tech milling machine to meet the requirements of coarse powder processing customers. 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.

MSB Coarse Powder Mill is used for pre-processing of various crushable non-flammable and non-explosive brittle materials with Mohs under 9. It is widely applied in quartz sand,silica sand,foundry sand,fine sand and other sand abrasive industry. It is also applied in industries of mining , construction , metallurgic,road building and water conversancy etc.

1. High efficiency of spare parts. As materials fall from top to bottom, roller and ring are equally worn. Thus the life span could be 3 times higher than that of Raymond Mill.
    2. High efficiency of processing fine sand. 80% of the finished sand could be finer than 1-2mm.
    3. This machine could be used as the pre-grinding equipment before ball mill so as to increase Ball Mill efficiency by 50%.

Step with main shaft, bulk disk and roller bracket is driven by motor through reducer. Installed above bracket, roller assembly rates with main shaft and swings freely meantime. This bring a large centrifugal force, which scatters bulk materials evenly in grinding intermediate layer between central roller and ring. The bulk materials are grinded into powder and fall on the bottom, and then discharged from discharging opening under the effect of synchronously rotating scraper.
