The Working Principle of Vertical Mill
Vertical mills have become an essential part of modern powder - processing industries. This article focuses on the in - depth exploration of their working principle.
At the heart of a vertical mill, there is a large rotating table. The raw materials are fed onto this table. As the table rotates, the materials are pushed towards the outer edge by centrifugal force. Around the table, there are grinding rollers that are pressed against the materials. These rollers are either spring - loaded or hydraulic - actuated to ensure a consistent and effective grinding pressure.
The grinding process is a combination of rolling and crushing. When the materials pass through the gap between the rotating table and the stationary grinding rollers, they are ground into fine powder. Then, an air stream is introduced from the bottom of the mill. This air stream carries the ground powder upwards.
Larger particles that are not fully ground fall back onto the table for further grinding, while the fine powder is carried out of the mill and collected through a dust - collection system. This continuous cycle of grinding, separation, and collection makes the vertical mill highly efficient in powder production.
