Milling Technology Selection For Particle Size Reduction
Classifier mills are a type of rotary impact mill (referred to above) which have the benefit of being a single machine with an integrated impact mill and classifier in the one housing. The CLM mill is commonly used for multi-stage, closed loop grinding and is ideal for products with properties of a more challenging nature and/or requiring a tightly controlled particle size distribution (see

Analysis of grinding kinetics in a laboratory ball mill using
2019/11/1In addition to the ball mill, simulation of various milling equipment such as centrifugal mill, stirred mill and planetary mill were also studied. For example, Mori et al. studied the correlation between impact energy and grinding rate for a wet ball mill and reported that the grinding rate can be predicted through the measured impact energy using DEM.
