LM Series Vertical Mill


Introduction:

LM Series Vertical Mill is using top technology of world class level , it is a new type advanced machine. LM Series Vertical Mill can crush and grind many kinds of materials including granular and powdered materials.Cement, power, chemical industry are in great need of good quality grinding mills .

Products features :
  1. LM Series Vertical Mill system joins crushing, drying, grinding and classifying together.The machine can be installed outside and saves occupation area.
  2. It saves energy. By regulating the air temperature while working .
  3. It is able to reduce duplication of milling, stable product quality.
  4. The device is fast to replace the roller sleeve, and liner, and reduce the downtime loss.
Working principle:

The motor drives the grinding table through decelerator. Hot air comes into the mill from the air inlet. The materials are pulverized by the roller when by pass of the groove on the grinding table. The coarse powder fall down the grinding table for regrinding under the function of rotation rotor. The fine powder comes out with the airstream,and is gathered by the dust catcher. By adjusting separator, it can reach proper fineness of materials.
