1100M - 2800M Coal Vertical Mill For Cement /Chemical Industry /Coal Power

Description:

Vertical mill, also known as roller mill, is widely used in large-scale material grinding and ultra-fine grinding processing in cement chemical, coal, electric power and other industries. It is an ideal equipment for the integrated grinding industry. It can be used in the preparation of pulverized coal to make the product fineness meet the industry standard.

Capacity: different materials, different processing capacity, see the technical parameter table below for details

Applicable materials: vertical roller mill mainly grinds raw meal, clinker, mineral powder, slag, granulated blast furnace slag, limestone, coal powder, coke powder, coal gangue, fly ash, pozzolan, gypsum, calcite, pyrophyllite, clay , sand, bauxite, silica fume, etc.

Application Industry: cement chemical, coal, electric power and other industries.

Technical Parameter

Outstanding advantages

Vertical mill is an ideal large-scale grinding equipment, which is widely used in cement, electric power, metallurgy, chemical industry, non-metallic mining and other industries. It integrates crushing, drying, grinding, grading and conveying, and has high production efficiency. It can grind block, granular and powdery raw materials into required powdery materials.

1. High grinding efficiency and low power consumption;
2. Less metal consumption per unit product;
3. The technological process is simple, and the functions of material grinding, drying and powder selection are completed at the same time;
4. 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.

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.

Feature:

1. Grinding disc: including guide ring, wind ring, retaining ring, lining plate, disc body, scraping plate and lifting device, etc.
2. Grinding roller: The roller sleeve is an easy-to-wear part, which requires sufficient toughness and good wear resistance.
3. Powder separators can be divided into three categories: static, dynamic and high-efficiency combined powder separators
4. Pressurizing device: hydraulic device, accumulator.
5. Monitoring device: rocker monitoring, vibration monitoring.
6. Transmission: electric motor, reducer.
7. Water spray system: reduce the temperature and stabilize the material layer.
8. Coarse powder external circulation system: elevator.
