Description
Cement Vertical Mill
【Product introduction】
Cement vertical mill, also known as cement roller mill, is widely used in large-scale material grinding and ultra-fine grinding in cement chemical, coal, electric power and other industries. It is an ideal equipment for the milling industry that integrates grinding, grading and conveying. It is used in the preparation of pulverized coal to make the product fineness meet the industry standard.
【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.
【Production Capacity】

【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.
【Structure and composition】
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.
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.
