LM Vertical Roller Mill
LM series vertical roller mill, which is developed and launched by Zenith, sets medium crushing, drying, grinding, classifying and other functions as a whole, being the ideal equipment in the grinding industry.
Grinding is the required powdering or pulverizing process when final size of below 2 mm is needed. Zenith can provide the proper grinding measure to all kinds of methods and application.
Features
- Low running costs: LM vertical roller mill 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;
- Simple and reliable operation: LM vertical roller 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;
- Energy conservation and environmental protection: LM vertical roller mill features small vibration, low noise, and sealing device as a whole, and the system also works with no pressure and dust spills.
