MSB Coarse Powder Mill Overview
msb coarse powder grinding millMSB Coarse Powder Mill is a kind of new high-tech grinding mill to meet the requirements of sand processing customers. Based on over 30 years’ research experience of our experts in the grinding mill industry and considering recommendations & requirements of domestic and foreign clients, it is the ideal equipment to replace Raymond Mill, Trapezium mill, ball mill, and other traditional grinding mill which only process powder materials. By being a component of closed production lines, coarse powder grinding mill can produce various size products of better effect.
MSB Coarse Powder Mill Application
Coarse powder mill is high-efficiency equipment and widely applied in quartz sand, silica sand, foundry sand, fine sand and other sand abrasive industry.
MSB Coarse Powder Mill Main Features and Benefits
  1. Coarse powder mill is with 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 coarse powder grinding mill
  3. The coarse powder grinding mill is a highly efficient desulfurization equipment of power plant. It can grind CaCO3 into fine powder less than 1-2mm, the desulfurization effect is better;
  4. This coarse powder grinding mill can be used as pre-grind equipment before ball mill; the ball mill efficiency will increase 50%;
  5. Products out of coarse powder grinding 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.
MSB Coarse Powder Mill Working Principle
Step with main shaft, bulk disk and roller bracket is driven by motor through reducer. Installed above bracket, roller assembly rotates 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 in the coarse powder grinding mill are grinded into powder and fall on the bottom, and then discharged from discharging opening under the effect of synchronously-rotating scraper.
MSB Coarse Powder Mill Repair And Maintenance
