Brief Introduction: MSB Coarse Powder Mill series is a kind of new high-tech milling machine to meet the requirements of sand processing customers. Based on our experts?several 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, mill, ball mill, and other traditional which only process power 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. 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 are grinded into powder and fall on the bottom, and then discharged from discharging opening under the effect of synchronously-rotating scraper. Main Performance Parameters: Model: MSB1004 Roller quantity: 4pcs Max. feeding size: <30mm Too hard material<20mm Product size : 70-90%<2mm Capacity: 8-15ton/hour Relative to average size and hardness of feeding material Main motor power: 37-45kW Use small motor if use fine material and want low capacity Main motor model: Y2-225M-4 45 kW Overall size(L譝譎): 1.87?.5?.58(m) Including main motor, decelerator and main unit Largest single pc weight: 900kg Total weight(excluding electricity control cabinet) 8ton
