Grinding Mill. Grinding mills are mainly used in metallurgy, building materials, chemical engineering, mines and other fields. The grinding mill is a collective word which can be classified into the vertical grinding mill, the pendulum roller mill, the superfine grinding mill, the trapezoidal grinding mill, the medium-speed grinding mill and so on.
roller mill on the 1M and 2M passages of the reduction system have been investigated. At the same roll gaps and under the same sieving conditions, the lower flour yield has been obtained using an eight-roller mill compared to the conventional milling system (5-8 %) followed by a higher energy requirements for grinding.

They have lower specific energy consumption than ball mills and the separator, as in raw mills, is integral with the mill body. In the Loesche mill, Fig. 2.23, 16 two pairs of rollers are used. In each pair the first, smaller diameter, roller stabilises the bed prior to grinding which takes place under the larger roller.

mills, the induced micro cracks generally result in a reduction of the Bond Work Index. For most ores this reduction is in the range of 10 – 25%. This directly translates to either an increased throughput of the grinding circuit or a reduced power consumption at similar throughput rates, which will reduce the required number of mills.
