LM Vertical Grinding Mill

LM vertical grinding mill is developed and designed by Zenith. it sets medium crushing, drying, grinding, classifying and other functions into a whole, being the ideal equipment for grinding various kinds of materials.Already be proven commercially, the LM vertical grinding mill presents a major advance in roller mills for finish grinding process.

With the customer feedback information,we develop and promote the function of a new generation of more complete powder series products,That is LM vertical grinding mill.It sets medium crushing, drying, grinding, classifying and other functions as a whole, being the ideal equipment in the grinding industry.

LM Vertical Grinding Mill Major Advance For Grinding Mill

  1. Integrating a variety of functions.LM vertical grinding mill is equipped with a classifier,you can determine the production of finished powder fineness by adjusting the classifier blade.
  2. Installation of hot blast stove can be of high moisture materials drying and processing first, greatly enlarge the range of processing material, but also improve the efficiency of the grinding powder, protecting the flour mill.
  3. Low running costs.It adopts the technology that vertical roller grind material directly on the disc, with low energy consumption; for the roller is not contact with the disc directly in the work, and the roller and liner are made by quality materials, it is of less wear and long life.
  4. Simple and reliable operation.Vertical grinding mill's automatic control system can reach remote control, which is easy to operate; there is the device to prevent roller sleeve contact with disc liner directly, and avoid the destructive impact and severe vibration; we can turn the rotating arm by repairing fuel tank, replace the roller and liner are more convenient, which can reduce the downtime.
  5. Energy conservation and environmental protection.Vertical mill features small vibration, low noise, and sealing device as a whole, and the system also works with no pressure and dust spills.
