Vertical grinding machine is based on the extensive use of domestic and foreign advanced technology, combined with many years of experience in the production of various vertical grinding machine, the design and development of advanced grinding equipment. Is a set of crushing, drying, grinding, grading transport in one of the grinding industry ideal equipment. It can be widely used in cement, electric power, metallurgy, chemical industry, non-metallic ore and other industries. Used for grinding bulk, granular and powder raw materials into required powder materials.

Vertical grinding machine is mainly composed of powder separator, grinding roller device, grinding disc device, pressure device, reducer, motor, shell and other parts. Separator is a kind of high - efficiency and energy - saving powder sorting device. The grinding roller is used to crush and crush the material. The grinder is fixed on the output shaft of the reducer, which is the place where the grinding roller presses the material. The pressurizing device is the component that provides grinding pressure for the grinding roller, which provides sufficient pressure for grinding materials.

When the large vertical grinding machine is working normally, the motor drives the grinding disc to rotate through the reducer, and the material falls into the center of the grinding disc through the locking air feeder, while the hot air enters into the grinding from the air inlet. As the rotation of mill material under the action of centrifugal force, the mill edge, after the ring groove on the mill roller rolling and crushing, after crushing material on the edge of the mill bring up by the wind ring of high-speed flow, larger particles directly into a millstone to grinding, flow of material through the upper separator under the effect of rotating rotor, coarse powder from the cone hopper fall to mill grinding, qualified fine powder with airflow grinding, through collecting dust collecting device, namely for the product, material containing water is in the process of contact with the hot air flow drying, by adjusting the hot blast temperature, can satisfy the requirement of different humidity material, Achieve the desired product moisture content. By adjusting the separator, the thickness required for different products can be achieved.
