Vertical roller mill is one advanced mill, adopting top technology domesic and abroad, and based on many years’ mill experiences. It can crush, dry, grind, and classify the materials. Vertical roller mill can be widely used in such industries as cement, power, metallurgy, chemical industry, non-metallic mineral. It is used to grind granular and powdered materials into powder with required fineness.
Vertical roller mill Technical Advantages
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
(1) 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%.
(2) 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
(1) It is equipped with automatic control systems, so remote control makes it easy to operate.
(2) 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.
