In the mining industry, vertical roller mills are mainly used for mineral processing and extraction. It can grind ore and slag into fine powder to facilitate the subsequent mineral processing and extraction process. Compared with traditional ball mills, vertical mills have higher grinding efficiency and lower energy consumption, thus greatly improving production efficiency and reducing production costs.
Vertical roller mills are widely used in various industries due to their high efficiency, energy saving, environmental protection, and other characteristics, and provide strong support for the production and development of various industries. At the same time, with the continuous advancement of technology and the continuous development of the market, vertical mills will continue to be optimized and upgraded to provide more high-quality and efficient solutions for the grinding needs of various industries.

The working principle of a vertical roller mill, that is, a vertical roller mill, is mainly based on the interaction of materials between the grinding disc and the grinding roller. The specific process is as follows:
The motor drives the grinding plate to rotate through the reducer, and the material falls into the center of the grinding plate from the feed port through the air-locked feeder. As the grinding disc rotates, the material moves toward the edge of the grinding disc under the action of centrifugal force. In this process, when the material passes through the annular groove on the grinding disc, it is crushed by the grinding roller and crushed. The crushed materials are picked up by the high-speed airflow of the wind ring at the edge of the grinding disc, and the large particles fall directly to the grinding disc for re-grinding, while the materials in the airflow enter the separator.
In the separator, the material passes through the action of the rotating rotor, and the coarse powder falls from the cone hopper to the grinding disc for re-grinding, while the qualified fine powder comes out of the grinding along with the airflow and is collected by the dust collection device, which is the final product. In addition, the vertical mill is also equipped with a hot air device for drying the materials. Hot air enters the mill through the air inlet and exchanges heat with the materials, causing the moisture in the materials to evaporate quickly to meet the requirements of materials with different humidity.
