Impact Classifier Mill ICM

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.

Highly Selective Classification with Impact Classifier Mill

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 regarding flow capacity, color intensity, shine, applicability and taste.

The typical impact classifier mill applications are in the areas of chemicals, pigments, powder coating, minerals, coal, food, sweets, cosmetics and pharmaceuticals.

Easy Operation and Cleaning

Our impact classifier mill is available with the proven direct drive, making it easy to operate and equally simple to clean.

Optionally, a pressure shock resistant impact classifier mill is available as a PSR 11 version (pressure shock resistant up to 11 bar). The robust construction of the PSR 11 version is required everywhere where explosions may occur, for example when grinding sugar, shavings, powder coating, coal, etc. Our ICM can easily be inserted in ATEX-compliant systems.
