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

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Loesche developed the 4roller coal grinding mill with four tried and tested modules for throughputs over 150 t/h. The development was first realised in 1970 for grinding mills in the cement industry. This number of rollers also enables operation with only one pair of rollers to increase control response availability and flexibility.
Abstract: The quality of powder of nonmetal materials directly relates to the force exerted on grinding roller, while the force on grinding roller relates to the thickness of the material layer. The uneven pressure distribution between the roller and material layer is caused by the drumshaped characteristics of vertical mill grinding roller.
