Vertical Mill Overview
LM series Vertical Grinding 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 grinding 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 meets the requirement of clients in the high production of powder, and its main technical and economy indicator reachs the international level.
Vertical Mill Application
LM series vertical mill (Vertical mills) can be widely used in cement making, power,metallurgy, chemical and nonmetalliferous ore industries. The Vertical mills are used to grind lumpy, granular and powdery materials to the required size.
Specialized for the high production of superfine pyrophyllite powder making in glass fiber industry;
Specialized for the high production of gangue powder making in coal industry;
Specialized for the high production of various of chemical raw material powder making in the chemical industry.
The Vertical mills are necessary equipments for the high production of mineral powder in the non-mental mine industry and large scale powder making in many other industries.
Ball Mill Features
1. Low operating costs
Combine the crushing, grinding, dring, 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 more longer.
4. High dring 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 diffirent humidity.
5. Simple and reliable operation
Automatic control system is equiped, so the remote control makes it easy to operate. Vertical roller mill is equipmented 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 reparinging 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.Vertical Mill Data
