Cement Vertical Roller Mill for cement industry
Description of Cement Vertical Roller Mill :
Cement Vertical Roller Mill is one of the most important cement equipment. It is the key grinding machine of materials being crushed. The cement grinding mill plays a vital role in cement production line and cement production process. Cement mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, ferrous and non-ferrous metals beneficiation, ceramics and other production industries. It makes dry or wet grinding for all kinds of ores and other grind-able materials.
Structural features of Cement Vertical Roller Mill:
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 the outdoor installation that reduce a large number of investment costs.
Low Operation Cost
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%. 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 time is long. 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.
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.
Maintenance Convenience
By repairing fuel tank, rotating the arm, it is fast to replace the roller sleeve, and liner, and reduce the downtime loss.
Work Principle of Cement Vertical Roller Mill:
When it works, raw materials are fed in evenly by the feeder at the bottom of the hopper, then lifted to appropriate height by the bucket elevator, then sent into the mill through feeding pipe to be grinded , the grinded materials are brought into the powder classifier by the hot air generated by the hot air stove, at the same time, the materials are dried and classified , the unqualified materials fall down to be regrind, qualified fine powders are sent into powder collector , and then transported to the storage by the conveyor.
