It integrates crushing, drying, grinding and classifying conveying into a whole, has high production efficiency, and can grind the block, granular and powdery raw materials into required powdery materials.

The working principle of the vertical mill is that a motor drives a grinding disc to rotate through a speed reducer, materials fall to the center of the grinding disc from a discharging opening, move towards the edge of the grinding disc under the action of centrifugal force and are crushed by a grinding roller, the crushed materials overflow from the edge of the grinding disc, meanwhile, the crushed materials are brought into a high-efficiency powder selecting machine integrated with the vertical mill by a high-speed upward hot air flow from a nozzle ring (an air ring), coarse powder is returned to the grinding disc after being separated by a separator, and the crushed materials are ground again; the fine powder flows out of the mill along with the air, and is collected in a dust collecting device of the system, thus obtaining the product. Coarse particle materials which are not carried up by the hot air flow and metal parts which are accidentally entered are sunk from the wind ring, scraped by the scraping plate, and fed into the mill through the bucket elevator with external circulation for grinding again.

The vertical mill is provided with a feeding pipe which is used for feeding materials into the vertical mill in a tilting manner, and in the use process of the conventional vertical mill feeding device, when the feeding amount of the materials is accidentally too large, the materials are easy to block in the feeding pipe, or when the humidity of the materials is large, the materials are easy to adhere to the inner wall of the feeding pipe, so that the blocking probability is improved.
