Coal Pulverizer VRM Vertical Roller Mill For Grinding Limestone Dolomite 90kw

Vertical Roller Mill Supplier Coal Vertical Mill For Grinding Limestone Dolomite

Description:

HVM vertical mill is a kind of safety, environmental protection, energy saving and high efficiency designed and developed after painstaking research. It is widely used in large-scale material grinding and ultra-fine grinding in cement chemical, coal, electric power and other industries. , is an ideal equipment for the grinding industry that integrates crushing, drying, grinding, grading and conveying. It is used in the preparation of pulverized coal to make the product fineness meet industry standards.

Capacity: Different materials, different processing capacity and different output, please refer to the following technical parameter table for details

Technical Parameter

Working Principle:

The motor drives the grinding disc to rotate through the reducer, the material falls into the center of the grinding disc from the feed inlet, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, the material moves to the edge of the grinding disc, and is crushed by the grinding roller when passing through the annular groove on the grinding disc. The crushed material is carried by the high-speed airflow at the air ring at the edge of the grinding disc, and the large particles fall directly on the grinding disc. Re-grinding, when the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls on the grinding disc for re-grinding, and the qualified fine powder is ground together with the airflow and collected in the powder collecting device, which is product. Moisture-containing materials are dried during contact with hot gas to achieve the required product moisture.

Advantages

• High grinding efficiency and low power consumption;
• Less metal consumption per unit product;
• The technological process is simple, and the functions of material grinding, drying and powder selection are completed at the same time;
• Small footprint, compact layout, light weight of system equipment, and low investment in civil construction.

The vertical pulverizer is composed of grinding disc, grinding roller, powder separator, pressure device, monitoring device, transmission device, water spray system, coarse powder external circulation system, etc.
