Vertical Coal Mill

Vertical mill outline

LM series vertical mill is a kind of large scale powder mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. With a decade of years research of mills, vertical mill is designed and manufactured based on our advanced design idea, and in combination with the European technology and the market demand.

LM vertical roller mill adopts reliable structure and reasonable process flow, integrated with drying, milling, classifier, and elevator. Especially, it can fully meet the requirement of clients in the high production of powder, and its main technical and economy indicator reaches the international level.
Vertical mill details

Application area: Glass fiber industry, coal industry, chemical industry, and for large scale powder making and non mental mine industry.

Successfully grinded material: Pyrophillite, coal, calcite, barite, limestone, lime powder, marble, silica, talc, kaolin, gold ore, ferrite, clay, slag, marble, and so on.

Material requirements: max feeding size less than 55mm

Components of grinding line: Vertical mill plant is made up of feeding part, discharging part, gyre part, grinding table, decelerator, and roller and so on.
Vertical mill features

1. Low operating costs. Combine the crushing, grinding, drying, classifier and elevator, the system of vertical mill is simple and occupation area is about 50% of ball mill system. Vertical roller mill can be installed outside, so it will reduce a large number of investment cost.
2. High efficiency. Compared with ball mill, vertical mill can save energy consumption 30%-40%.
3. Less wear and tear. The optimized roller and the high quality raw material make the machine’s life longer.
4. High drying ability. As the hot air inside contacts directly with the material, drying ability is higher, and it saves energy. By regulating the air temperature, it can meet requirements with different humidity.
5. Simple and reliable operation. Automatic control system is equipped, so the remote control makes it easy to operate. Vertical roller mill is equipment with one device, which prevents the roller from contacting with the liner directly, and avoids the destructive impact and severe vibration.
6. Convenient maintenance. By repairing fuel tank, rotating the arm, it is fast to replace the roller sleeve, and liner, and reduce the downtime loss.
7. Environmental protection. Vertical roller mill is with small vibration, low noise, and the overall sealing. The system works under negative pressure, so there is no dust going out. It meets the requirements of the state Environmental Protection.
