[0002] Vertical mill is a kind of equipment used for grinding. It can grind granular or block raw materials into powder materials of required size. It is widely used in metallurgy, chemical industry, cement and other industries. The raw materials are put onto the grinding disc through the discharge pipe of the vertical mill, and then the raw materials are gradually turned into powder under the grinding between the grinding disc and the grinding roller. Finally, the powder materials are discharged from the vertical mill driven by the upward airflow.

[0003] The vertical mill feeding method in the prior art is the center feeding method, but it has some disadvantages: when the material is dropped to the center of the vertical mill grinding disc, it is easy to cause accumulation, so that the material cannot slide smoothly to the surrounding of the vertical mill grinding disc, reducing the grinding efficiency. When feeding the material into the vertical mill, the material hits the grinding disc of the vertical mill and is easy to bounce out of the vertical mill, posing a safety hazard. Therefore, improvements are needed. Utility Model Content
