Vertical Grinding Mill Series LM - Vertical Roller Mill is a new kind of large scale power mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. Based on many years’ mill experiences, Vertical Mill series LM has been adopting top technology domestic and abroad, which can provide crushing, drying, grinding, and classifying process.
Vertical roller mill is a necessary equipment for the high production of mineral powder in the non-mental mine industry and large scale powder making industry and in many other industries.
Vertical milling machine series LM is widely used in cement, power, metallurgy, chemical industry, non-metallic mineral. It is used to grind granular and powdered materials into powder with required fineness.
The Advantages of Vertical Mill Series LM
1.Low Investment Cost
This mill itself can crush, dry, grinding, classifying, so the system is simple, and occupation area is about 50% of ball mill system. In addition, it can be installed outside, so it will reduce a large number of investment costs.
2.Low Operation Cost
⑴ High efficiency: roller compacted materials directly onto the grinding disc, so power consumption is low. Compared with ball mill, it saves energy consumption by 30% ~ 40%.
⑵ Less wear and tear: As the roller is not in direct contact with the disc, and material of the roller and liner is high quality, so life lime is long.
3. 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 diffirent humidity.
4. Simple and reliable operation
⑴ It is equipped with automatic control systems, so remote control makes it easy to operate.
⑵ It is equipmented with one device,which prevents the roller from contacting with the liner directly, and avoids the destructive impact and severe vibration.
5. the stability of product quality
As the material stays in the mill for a short time, it is easy to detect and control the product particle size and chemical composition, to reduce duplication of milling, stable product quality.
6. Maintenance convenience
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
It 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.
Working Principle of Vertical Mill Series LM
Vertical MillSeries LM is an advanced grinding machine integrated with drying milling grading and transporting. It is a high standard mill which can meet the high capacity of powder producing request. Vertical MillSeries LM is widely used in cement, powder station,metallurgy, chemical and non-metal industry.
