LM vertical roller mill is mainly responsible for the grinding operation of the concentrator. It is a key link of the beneficiation process and accounts for a large proportion in the infrastructure investment and production cost of the whole concentrator.

At the same time, LM vertical roller mill is also the "bottleneck" operation link of the whole concentrator. It is directly related to the overall processing capacity of the concentrator and has a significant impact on the economic and technical indicators of the whole concentrator.

Therefore, ensuring the output of LM vertical roller mill to meet the standard is the top priority in concentrator production, it is a very common problem that the output of LM vertical roller mill fails to meet the design requirements.
