The particle shape of the materials from the roller press and the vertical roller mill is also different. The vertical mill grinds the material by two forces, the extrusion force and the shearing force between the roller and the grinding disc; the roller press grinds the material by only one force, the force between the two grinding rollers.
This range was established by conventional grinding in 2 chambers ball mill before acceptance of newer technology like Vertical Mill Roller Press technology. Semi-finish grinding in roller press has ball Mill along with roller press and therefore offers best particle size distribution (comparable to ball mill product). However, in the …

The primary grinding is done by the Roller press and finish grinding takes place in Ball mill. Because of this, we can increase the Ball mill capacity as well as the Cement production. Also the feed materials which are coming from roller press to the ball mill are powdery form instead of Clinker material.
In a ball mill, the grinding process takes place by impact and attrition. On the other hand, a vertical roller mill exposes a bed of material to a pressure high enough to fracture the individual particles in the bed. This process creates a stable and consistent grinding bed between the rollers and the VRM table.
