LUM Vertical Roller Mill Little abrasion wear, Long service life Based on 30 years of development experience of grinding equipment, Liming Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn’t contact with millstone usually, which makes abrasion little and service life longer. Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on. Learn More About Liming® LUM Series Superfine Vertical Roller Grinding Mill 1. High grinding efficiency, little pollution to the final products. 2. Advanced, efficient and energy-saving powder-concentrating technology. 3. Secure and efficient operating principles, intelligent operating system. 4. Little attrition. 5. Convenient and easy to maintenance. 6. Environmental friendly. Working Principle The main motor drives the millstone to rotate through the reduction box, meanwhile, the air flow gets into the mill through air intake. The materials come out of the screw feeder and fall on the center of the millstone, and then they will move from the center to the edge of the millstone under the affect of centrifugal force. When they move across the grinding zone, they will get grinded by the rollers. Those materials in big pieces will be crushed and grinded directly while those small ones will get extruded and they will form a material bed in which intergranule and mutual grinding will take place.
