Application of vertical roller mill in cement building materials industry
Because of its good performance, vertical roller mills are widely used in the grinding and ultra-fine grinding of various solid materials in cement, building materials, electric power, metallurgy, chemical, non-metallic minerals and other industries.
As the demand for cement continues to increase, the cement industry continues to grow and develop, and the application of “cement grinders” has begun to become more widespread. The key equipment “cement grinder” included in a complete cement production line.
The cement vertical mill is the key equipment in the cement production line. As the cement industry continues to grow and develop, the cement vertical mill is more and more widely used. In order to let customers have a deep understanding of the cement vertical mill, select the cement vertical mill, and today we will explain in detail the working principle of the cement vertical mill.
The motor drives the grinding table to rotate through the reducer, and the material falls from the feeding opening to the center of the grinding table, moves to the edge under the action of centrifugal force and is crushed by the grinding roller, and the pulverized material overflows from the edge of the grinding table and is simultaneously from the nozzle ring ( Wind ring) The high-speed upward hot air is brought to the high-efficiency classifier integrated with the vertical mill. The coarse powder is sorted by the separator and returned to the grinding table for re-grinding; the fine powder is ground with the airflow, in the system Collected in the dust collection device, which is the product. The coarse-grained material that has not been taken up by the hot air flow and the accidentally entered metal parts fall from the wind ring, and after the scraping plate is scraped off, it is fed again into the grinding machine by the externally circulating bucket lifter.
Nowadays, cement vertical mills have become an indispensable important equipment in cement production lines.
