Cement grinding Vertical roller mills versus ball mills

The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the majority of

Advantages of vertical roller mills compared to ball ...

First, the vertical mill is compared to the grinding media of the ball mill. The vertical self-grinding machine, as the name suggests, is a medium-free grinding machine that does not require steel balls, steel bars, etc. The material to be crushed is itself a crushing medium. This can effectively reduce the iron pollution of the finished product.
