LM Vertical Grinding Mill

LM vertical grinding mill is applicable to the cement industry raw material industries; coal mill coal preparation can be widely used in cement, power, steel, metallurgy, building materials, chemical industry; difficult for steel mill, ironworks grinding slag, slag, also suitable for cement clinker and other chemical raw materials. LM series vertical milling machine, 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. According to customers' requirements, Shanghai Zenith success in absorbing foreign experience and world-advanced technology, and in producing our vertical products, with self-owned intellectual property right. Now it has wide application in metallurgy, construction, chemical and mining industries, being the preferred equipments in grinding industry.

LM Vertical Grinding Mill Applications

LM series vertical mill is widely absorb advanced technology on the basis of well-known international companies, combined with our thirty years of experience in milling equipment, a set of design and development of crushing, grinding, separator, drying, material handling five functions in one integrated large-scale grinding equipment, with centralized process, small footprint, low investment, high efficiency, energy saving, environmental protection and many other characteristics. Vertical roller mill during the grinding operation, good performance, and this is its grinding principle is inseparable during the grinding operation, it will have a good performance.

  1. 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.
  2. Simple and reliable operation. 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.
  3. Energy conservation and environmental protection. It features small vibration, low noise, and sealing device as a whole, and the system also works with no pressure and dust spills.
  4. Small occupation area Low investment cost. Low operation cost and long service life. High grinding efficiency.
  5. Excellent drying function. Good final products quality. Easy to maintain.
  6. Environmentally friendly. High classifying capacity.
