Grinding Vertical Roller Mill Features
The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room. Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably. Compared with other milling plants, its passing ratio achieves 99%, this is what other mill can not reach. From crushing of raw material to grinding and packing is an independent production system.
Working Principle
Grinding Vertical Roller Mill Working & Running
How grinding vertical roller mill works?
Grinding Vertical Roller Mill works / runs by the following : The motor of this vertical roller mill drives the grinding table through decelerator. As the raw materials drop down the center of grinding table from feeds opening, hot air comes into the roller mill through the air inlet. Raw materials inside the vertical mill move to the edge of the grinding table since of the centrifugal force. While passing the groove on the grinding table, the raw materials are pulverized by the roller. The particles crushed by our vertical mill are lifted up by vane high-speed airstream. And at the same time the larger particles fall down to the grinding table for regrinding. The materials in the airstream pass the separator on the top of the vertical mill, while the coarse powder fall down the grinding table for regrinding under the function of rotation rotor. In this way,the fine powder comes out with the airstream,and is gathered by the dust catcher of the vertical mill. When the hot airstream inside the vertical mill meet the materials content with moisture,the latter will be dried.Through adjusting the temperature of the hot airstream, our vertical mill can meet different material's requirement; Through adjusting seperator, our vertical mill can reach proper fineness of materials.
