LM vertical grinding 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. For those mining investors who want to get a cheap price and cost of mining grinder, Zenith's LM series vertical grinding mill can meet their particular requirements.
Application of LM Vertical Grinding Mill
LM vertical grinding mill is the newest grinding machine, which integrates the advanced international technology and years of rich experience. It is ideal equipment that integrates crushing, drying, grinding and grading conveyor all together. LM series Vertical mill is mainly applied in the grinding process of metallurgy, building materials, chemical, mining and other mineral industries, and suitable for grinding quartz, feldspar and other non-flammable burst materials whose Mohs hardness are below 9.3.
LM Vertical Grinding Mill Benefits and Advantages
- The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. From the crushing of raw material to grinding and packing is an independent production system. Compared with other milling plants, its passing ratio achieves 99%, this is what other mill cannot reach.
- It features small vibration, low noise, and sealing device as a whole, and the system also works with no pressure and dust spills.
- Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reably. The electric control system is centrazed controlled, so the automaticity is high, no people are needed in the operating room.
- Its 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.
