LM Vertical Grinding Mills

LM Vertical Grinding Mills

LM Vertical Grinding Mills also called vertical roller mill, vertical roller mill is based on the principle of material bed comminution, the relative movement of the grinding roller and the grinding disc grinding materials, and by the hot air to ground material drying, with the grading device, in the grinding classification separator, coarse powder into the disc to be crushed; product by using air outlet outside the LM Vertical Grinding Mills by the bag dust collector. Our company based on extensive use of foreign advanced technology, combined with years of various grinding mill production experience, design and develop advanced grinding equipment .

Use of LM Vertical Grinding Mills

  • The cement plant raw material grinding.
  • The metallurgical, power, coal mill in cement industry.
  • kinds of non metal ore grinding.

LM Vertical Grinding Mills roller device

Adopt New type sealing device, the grinding roller reliable sealing, and no sealing fan, the grinding hypoxic, explosion suppression performance is superior.

LM Vertical Grinding Mills Selling point

  • reliable operation: automatic control system installation, can realize remote control, simple operation.
  • high performance: hot air in direct contact with the material in grinding, drying capacity, saving energy (for the mill system saves a dryer).
  • low input: set crushing, drying, grinding, grading conveying into a whole, compact layout, covers an area of approximately 50% milling system.

LM Vertical Grinding Mills characteristics

  • vertical roller mill with hydraulic pressure roller, and the hydraulic system with accumulator, therefore has the pressure is continuous and adjustable, pressure stability, small vibration grinding mill, quality reliable, stable yield;
  • vertical mill reasonable structure and the bed grinding principle, therefore, high grinding efficiency, low energy consumption than traditional 20-30% ball mill system;
  • LM Vertical Grinding Mills with hot gas conveying material, therefore, can be dry milling moisture content as high as 15% in the mill material, can save raw material drying system;
