Products Description
Bellian Cement Vertical Roller Mill is a large-scale grinding equipment developed by introducing international advanced technology. It integrates grinding, drying, classification and transportation, and is widely used in cement plants for grinding raw meal, clinker and slag. 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 cement production lines.
Working Principle
The vertical roller mill mainly consists of grinding table, grinding rollers, pressure device, classifier, motor and transmission system. 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. Hot air enters the grinding chamber from the air inlet, drying the materials while blowing up the ground powder. 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, compact structure, small floor area, low noise and less dust pollution.
Can vertical roller mill grind slag?
Yes, vertical roller mill is very suitable for grinding slag. It can produce high-quality slag powder with activity above 95%, which can be used as cement admixture to improve cement performance and reduce cost.
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. For raw meal grinding, the service life is about 1-2 years; for slag grinding, the service life is about 6-12 months. We provide all kinds of wearing parts with preferential prices.
Do you provide turnkey solutions for cement grinding stations?
Yes, we can provide turnkey solutions for complete cement grinding stations including vertical roller mill, separator, dust collector, conveying system and control system. From design to operation, we provide one-stop service.
