Products Description
Bellian Vertical Roller Mill is a large-scale grinding equipment developed by introducing international advanced technology, which integrates grinding, drying, classification and transportation. It is widely used in cement, electric power, metallurgy, chemical industry and other industries for grinding cement raw meal, clinker, slag, coal powder and other materials. Compared with traditional ball mill, the energy consumption of Vertical Roller Mill is reduced by 30-40%, and the floor area is reduced by 50%. It is the ideal equipment for large-scale powder production.
Working Principle
The Vertical Roller Mill mainly consists of grinding table, grinding rollers, pressure device, classifier, motor and transmission system. When the machine works, the materials fall onto the center of the rotating grinding table from the feeding port. Under the action of centrifugal force, the materials move to the edge of the grinding table and are crushed and ground by the grinding rollers. The hot air enters the grinding chamber from the air inlet, and the ground powder is blown up by the hot air and dried at the same time. The qualified powder is separated by the classifier and collected, while the unqualified powder falls back to the grinding table for re-grinding.

FAQ
What are the advantages of Vertical Roller Mill compared with Ball Mill?
Vertical Roller Mill has higher grinding efficiency and lower energy consumption (30-40% less than ball mill). It also has integrated drying function, can grind materials with high moisture content. In addition, it has compact structure, small floor area, low noise and less dust pollution.
Can Vertical Roller Mill grind hard materials?
Yes, Vertical Roller Mill has strong grinding force and can grind materials with Mohs hardness up to 9. It is suitable for grinding various hard materials such as iron ore, granite, basalt, etc.
What is the service life of grinding rollers and grinding table?
The service life of grinding rollers and grinding table depends on the hardness of the materials being ground. For soft materials like limestone, the service life is about 1-2 years; for hard materials like iron ore, the service life is about 6-12 months. We provide all kinds of wearing parts with preferential prices and fast delivery.
