Performance
1. The vertical structure makes the covered area small. And it integrates many functions in one complete set.
2. The two processes of grinding and powder selection can be realized by one device, which can reduce investment costs a lot.
3. The important parts are made of good quality steel, and the wear-resistant parts are made of high-performance wear-resistant materials. The whole machine has advantages of high wear-resistant performance, reliable operation and long wearing parts, high efficiency.
4. The fineness of the finished powder is uniform and the screening rate is high.
5. There is relatively low noise during production.
Working Principle
The slag vertical mill is a negative-pressure air-sweep type grinding equipment, which dries the slag and grinds the slag. When working, the main motor drives the grinding table to rotate through the reducer, and at the same time, the hot air enters the body of the vertical mill from the air inlet, and the material falls from the discharge port to the center of the grinding table. In the area of the upper grinding roller, it is crushed by the grinding roller, and the bulk material is crushed directly, and the fine-grained material is extruded to form a material bed for inter-particle crushing. The crushed material continues to move toward the edge of the grinding table until it is taken away by the strong air flow at the wind ring, and the larger particulate material falls back onto the grinding table to continue crushing. When the material in the air flow passes through the upper separator, the rotor under the action of the blades, the coarse particles are returned to the grinding table for grinding, and the qualified fine powder is discharged with the airflow and collected by the system's powder collector. The collected powder is the product of the vertical grinding. When the iron and other debris mixed with the material move to the edge of the grinding table with the material, they cannot be blown up by the wind due to their own weight.
