MSB Coarse Powder Mill is a kind of new and hi-tech milling machine to meet the requirements of coarse powder processing customers. Based on years' research experience in the milling industry and considering the recommendations and requirements of domestic and foreign clients. It is an ideal equipment to replace Raymond Mill, ball mill, and other traditional mill which can only process fine powder materials. It is a kind of 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 the closed production lines, it can produce all size of products with better effect.
Technical Advantages

1. High efficient of wear material, wear evenly, and its 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 in the power plant.
4. This machine can be used as pre-grind equipment before the ball mill.
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.

1) Driven by the motor through reducer , the bulk disk and roller bracket rotates synchronously with the main shaft.
2) Installed on the bracket, roller assembly rotates with main shaft and swings freely meantime, which brings a large centrifugal force, and then the scattered bulk materials are ground into powder.
3)The bulk materials are grinded into powder and fall onto the bottom, and then discharged from discharging opening under the effect of synchronously-rotating scraper.
