Vertical roller mill - Wikipedia Vertical roller mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dres
The discs of an attrition mill are generally in a vertical position so that materials not capable of reduction can pass by gravity out of the grinding area. 2.3 Roller Mills. A combination of cutting, attrition, and crushing occurs in roller mills.
tional ball-mill systems, high-pressure grinding rolls in every kind of design types and their various combinations with ball mills and, of course, VRMs vertical roller mills. All of these systems treat the material to be ground differently, in that the actual grinding needed to achieve the desired character-istics varies from one to the other.
Separation operation of vertical-roller-mill will be modelled by application of current models. The model shall enable the prediction of the throughput, the particle size distributions around the vertical-roller-mill circuit, the specific energy consumption and in a later stage the wear to be expected in dependency of ore treated.
