Vertical roller mill overview

Vertical roller mill is based on the extensive use of advanced technology, combined with years of various raw mill vertical milling machine production experience , design and development of advanced grinding equipment . Is a set of crushing , drying, grinding , grading conveyor in one of the milling industry ideal equipment. Vertical roller mill can be widely used in cement, power, metallurgy , chemical industry, non-metallic mineral industries. For the massive, granular and powdered materials ground into powder materials required .

Vertical roller mill is mainly composed of separator, roller device , disc device , pressing device , part of the reducer, motor , housing and so on. A splitter is a highly efficient , energy-saving separator device . Roller is used on the material compacted crushed parts. Disc fixed to the output shaft of the reducer , is where the roller compacted material . Pressurizing means is provided for the grinding pressure of the roller mill components , to provide sufficient pressure to crush the material to the grinding rolls .

What’s the vertical roller mill operation? When vertical milling machine to work properly, the disc drive motor through reducer rotating air lock feeder material through the inlet falls from a central disc , while hot air from the inlet into the mill . With the rotation of the disc , the material under the effect of centrifugal force , moving to the edge of the disc , the disc passes through the annular groove on the subject of rolling mill rolls and grinding , the material crushed by the wind at the edge of the ring disc with high-speed air from large particles fall directly on the disc re- grinding , material flow through the upper part of the separator , the rotation of the rotor in the role of meal fell from the cone disc re- grinding , qualified powder grinding out together with the air , through close dust collection equipment , namely products, materials containing moisture during contact with the hot gas stream was dried by adjusting the air temperature , the humidity of materials to meet different requirements, to achieve the required product water . By adjusting the separator can achieve the desired thickness of the different products .
