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. The classifier rejects particles which are too coarse. The coarse material is returned to the grinding zone for further particle size reduction.
The advantages of the ICM are its narrow particle size distribution and precise upper particle size restrictions of 10 μm to 2,000 μm. This allows for precise setting of the desired product properties with regard to flow capacity, color intensity, shine, applicability and taste.
