energy consumption is defined as the motor power consumed relative to the shell of the mill (a.k.a. power at the pinion output) divided by the fresh feed rate in dry tonnes per hour. The simplest models use a single grindability measurement to estimate the specific energy consumption across the whole size range observed in the industrial

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.
