01.04.2017· Effect of operational parameters on product size and product rate was investigated. Mineralogical analysis is a good way to evaluate the effect of vertical-roller-mill on downstream processes. For this specific ore the degree of mineral liberation is still to be determined. In previous works (van Drunick et al., 2010) an increase in the degree of mineral liberation by the usage of the

Vertical spindle roller mill Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravity-fed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.

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. These are smooth or corrugated rolls rotating at the same speed set at a pre-determined distance apart with material passing between the two. A
