  • Overview
  • Features
  • Working Principle
  • Specifications
LM vertical roller mill is a kind of high efficiency and energy saving product perfectly combined with 30 years of mature vertical grinding technology, foreign successful experience and our company's technical innovation and upgrading. It has realized the localization of world-class vertical grinding. It adheres to advanced powder making technology and multi-function, adopts reasonable and reliable structural design, and coordinates with advanced technological process. Its main technical and economic indicators reach the international advanced level.
  • 1.Low Operation Cost
     
    High efficiency and less wear and tear. Roller compacted materials directly onto the grinding disc, so power consumption is low. Compared with ball mill, it saves energy consumption by 30% ~ 40%. Material of the roller and liner is high quality, so life lime is long.
    2.High Drying Ability
     
    As the hot air inside contacts directly with the material, drying ability is higher, and it saves energy. By regulating the air temperature, it can meet requirements with different humidity.
  • 3.Environmental protection
     
    It is with small vibration, low noise, and the overall sealing. The system works under negative pressure, so there is no dust going out. It meets the requirements of the National Environmental Protection.
    4.Low Investment Cost
     
    This mill itself can crush, dry, grind, classify and transport, so the system is simple, and occupation area is about 50% of ball mill system. In addition, it can be installed outside, so it will reduce a large number of investment costs.
