The grinding approach in ball mills and vertical roller mills differ fundamentally. In the ball mill the comminution takes place by impact and attrition. The comminution within the vertical roller mill takes place by exposing a bed of materials to a pressure sufficiently high to cause fracture of the individual particles from the bed, although the majority of the particles inside the bed are considerably smaller compared to the thickness of the bed.

It is thus necessary that a stable and consistent grinding bed is formed between the rollers as well as the table of the vertical roller mill, capable to sustain such a pressure without the materials getting squeezed away from the pressure zone. A stable grinding bed is ordinarily simply obtained in raw materials grinding in the vertical roller mill with a high efficiency separator. However, in cement grinding it becomes a lot more difficult to kind a stable grinding bed.

In vertical roller mill, grinding is carried out primarily as a result of the application of compressive force vertically, the secondary effect currently being the horizontal shear force. The material to be ground is crushed between the rotating grinding track plus the individually guided grinding rollers. If you want to select one perfect vertical cement grinding mill, Daswell is often a appropriate choice for your cement production line.
