We usually adopt the powder mills for the industrial operation process. High efficient powder mills will make you feel relaxed and confident in your work. Based on 20 years research experience in the milling industry and considering recommendations and requirements of domestic and foreign clients, our company’s ultrafine mill has been the ideal equipment to replace the traditional Raymond mill, ball mill and other grinding mills which only process fine powder materials. Our company’s coarse powder mill is a kind of new high-tech milling machine to meet the requirements of coarse powder processing customers. Products out of our coarse powder mill can be used to make firebrick, concrete brick, block and other new building materials. This series of coarse powder mill has three unique features: 1.High efficiency of processing fine sand: 80% of the finished sand could be finer than 1-2mm. 2.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. 3.The mill could be used as the pre-grinding equipment before ball mill so as to increase the grinding efficiency by 50%. Our ultrafine mill can be used widely in the coal ball milling plant, silica grinding plant, quartz grinding plant, manganese grinding plant, limestone powder plant, limestone grinding plant, iron ore grinding station, coal power plant, coal processing plant as well as the cement grinding plant etc.
