Top Supplier Vertical Mill Raw Milling Machine Vertical Roller Mill For Cement

Cement vertical mill is a kind of grinding equipment for grinding clinker, which integrates crushing, grinding, powder selection, drying and conveying. With the acceleration of urban construction, the demand for cement industry has correspondingly increased. As the main equipment of cement production lines, cement vertical mills should have a proper understanding of their working principles in order to find satisfactory cement vertical mills.

The raw material vertical mill is an honorary product launched by our company to solve the technical problems of low output and high energy consumption in the cement production process. It is a mature and high-performance grinding and drying equipment widely used in cement chemical industry, coal, power, etc. This product integrates many advantages such as drying, grinding, and powder selection, and has become the mainstream product in the cement grinding industry.

Working principle:

The electric motor drives the grinding disc to rotate through a reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the edge of the grinding disc, and large particles directly fall onto the grinding disc for re grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding disc for re grinding, and qualified fine powder is discharged with the airflow, Collect in the powder collection device, which is the product. Materials containing water are dried in the Contact process with hot gas to meet the required product moisture.

Characteristics and advantages of raw material vertical mill

1. High grinding efficiency of raw material vertical mill
The raw material vertical mill can increase the grinding force through hydraulic pressure boosting, thereby increasing production and improving grinding efficiency; At the same time, there is also a limiter device that only grinds the material to prevent accidental contact between the grinding roller and the grinding ring from causing equipment vibration or even wear.

2. Low operating cost of raw material vertical mill
(1) Low energy consumption: The use of grinding rollers to directly crush and grind materials on a grinding disc results in low energy consumption, saving 30% to 40% energy compared to ball milling systems.

(2) Less wear: Due to the fact that the grinding roller does not come into direct contact with the grinding disc during work, and the grinding roller and lining plate are made of high-quality materials, the service life is long and wear is minimal.

3. Easy maintenance of raw material vertical mill
Simply flip the rocker arm and replace the roller sleeve and lining plate, which is convenient and fast. At the same time, it reduces downtime losses and saves labor costs.
