At present, one of the main comprehensive utilization methods of industrial slag residue is grinding. For example, slag, steel slag, nickel slag and other fine powder after grinding are widely used. Therefore, more and more enterprises and individuals invest in industrial slag residue grinding production lines, such as slag. The output of micro-powder production line and steel slag micro-powder production line also ranges from 150,000 to 2 million tons per year, so how to choose the equipment of industrial waste slag grinding production line with an annual output of 200,000 to 1 million tons?

The grinding equipment includes vertical mills and ball mills. Generally, the grinding materials used for commercial concrete and cement mixtures are ground by vertical mills.

Compared with other grinding equipment, vertical mill:

1. The structure is compact, the grinding disc rotates quickly, and the grinding part adopts flat disc cone roller, which has high grinding efficiency.

2. Simple operation, stable operation and low vibration.

3. The late wear of the roller sleeve and the lining plate of the grinding disc has little effect on the output, and the output reduction rate is less than 5%.

4. Low metal consumption, normal use of grinding parts for more than 8000 hours, and easy repair.

5. It integrates grinding and drying, and can use auxiliary heat source to dry raw materials with moisture content of 15~20%.

6. The combined high-efficiency cage-type powder separator with dynamic and static combination is adopted. The raw meal fineness is strictly controlled and the adjustment is sensitive. The raw meal fineness is R80μm=10~15%, R200μm≤1.0%.

7. The grinding roller is lubricated by thin oil circulation; the grinding roller bearing seal adopts three fluororubber skeleton oil seals.

8. The area of the air ring and the height of the retaining ring can be adjusted according to the working conditions.

9. The grinding roller can be lifted and dropped by itself to realize no-load start; the grinding roller can be automatically turned out of the casing by the action of the oil cylinder, which is convenient for maintenance.

With an annual output of 200,000-1,000,000 tons of slag residue grinding production line equipment, the diameter of the vertical mill is generally 2.6-5.4 meters.
