LM Vertical
Roller Mill

LM series Vertical Roller Milling machine is one automatic grinding mill that features low operating cost and high efficiency. In this video you will see how it works and many successful cases.

Technology Advantages

It owns many independent patents, such as the integrated design of grinding and drying, the excellent grinding roll and grinding ring, and the overall design of sealing system.

  • Small floor space,low investment

    With an integral function of grinding, drying and grading, the mill covers a small area and can placed in the open air. In the meantime, the investment cost of the mill is low.

  • Low operation costs

    The rollers are equipped with roller sleeve, which can be replaced easily, the rollers are not easy to be worn out and so the cost is reduced.

  • Efficient pulverizing

    By pressurizing the hydraulic pressure, it is able to increase the pulverizing yield and improve pulverizing efficiency.

  • Strong drying ability

    With strong drying capacity, the mill can satisfy the requirements of materials with different moisture content through adjusting the temperature of hot air.

  • Stable quality

    Benefiting from special working principle design, over-grinding can't occur easily and the properties of materials are quite stable.

  • Environmental Protection

    The system is working under negative pressure environment, there is no overflow of the dust. Small vibration and low noise.

Grinding System

Full set of LM grinding equipment includes main unit, bucket elevator, raw material warehouse, belt conveyor, iron separator, intermediate bunker, closed type quantitative feeder, special pulse filter, fan, air valve, hot blast stove.

Production Case

LM vertical roller mill is applicable to powder pulverization in metallurgy, building material, chemicals mine, abrasive industry, ceramic industry and other industries.
