It is one complete plant that integrated with drying, milling, classifier and elevator. It is the high standard mill with many advantages, like taking a little space, high efficiency and energy-saving, and the LM Vertical Roller Mill fully meets the requirement of clients in the high production of powder.

According to LM mill’s different applications, it contains three series. LM-K mineral mill is suit for producing raw cement; LM-M coal mill fit for grinding coal powders and LM-N cement-slag mill is mainly used to pulverize hard materials, such as slag, cement clinker and many other chemical materials.It has the following features:
1.Low Investment Cost.This product sets crushing, drying, grinding, classifying and transportation as a whole, and it has simple system and compact structure, it takes 50% occupation area of ball mill and can be installed in outdoor sites, reducing the investment cost greatly.
2.Low Operation Cost.Because the rollers do not rub the grinding plate directly and both of them adopt the finest material, the service life is extended and the abrasion is reduced.
3.Excellent Drying Function.The inner hot wind can dry all the powders directly; this function not only helps investors save the investment cost of dryers and reduce the energy consumption. Different requirements of different moistures are easy to solved by adjusting the temperature of the hot wind.
4.Easy To Maintain.By controlling the hydraulic device and turning the lift arm, it is easy to replace the roller sleeves, grinding plates. In this way, both maintenance time and labor cost are saved.
5.Steady Performance.Limiting stoppers are equipped in this machine, they can protect the roller from impacting millstone device directly, averting devastating-impact and reducing the failure rate.

Motor drives millstone-device through reducer and the hot air comes into the machine from the air inlet. When the materials are fed to the centre grinding plate, they move to the edge of grinding plate under the action of centrifugal force. Then the material are grinded by the grinding rollers when they pass through the grinding zone. Crushed materials continue to move to the edge of the grinding plate until taken away by the airstream. The big ones fall down and the process of grinding continues. The qualified ones pass through the separator and are gathered by the collector.
