The impact classifier mill ICM is used for fine and finest grinding of brittle materials. During impact grinding, the grinding tools throw the feed material into the liner and crush it. Following this, the integrated classifier separates the material. The grinding fineness can be set there flexibly using the classifier's rotary speed.

Dynamic air classifier technology has been evolving since 1885 and nowadays their classification range changes between 300 μm and sub-micron (< 10 μm) with a specific type of classifiers [3]. Typically, dynamic classifiers have a rotating plate on which the material is poured and dispersed with the aid of centrifugal force.

Recommendations for achieve these goals in ball mill grinding circuit: In a plant with hydrocyclones is correct to use higher circulating load (~400%) to diminish residence time in the mill. For instance, versus 300% CL around 5% energy saving is obtained and the product has 5%-10% less -10um fraction (see 4th Grinding and Classification Law)
