Impact classifier mill for fine grinding of brittle materials
In industries such as chemicals, food, and pharmaceuticals, achieving fine and uniform particle sizes is crucial. Traditional methods may not provide the desired control over particle size distribution, resulting in inconsistencies in product quality.

Achieve precise particle size control
The Impact Classifier Mill ICM from Neuman & Esser is designed for fine and finest grinding of brittle materials. Utilizing impact grinding, the tools throw the feed material into the liner and crush it, while the integrated classifier separates the material. This allows for the grinding fineness to be flexibly adjusted using the classifier’s rotary speed. Particles that are too coarse are rejected and returned to the grinding zone for further reduction. One of the key advantages of the ICM is its narrow particle size distribution and precise upper particle size limits ranging from 10 μm to 2,000 μm, enabling the specific setting of product properties such as flow capacity, color intensity, gloss, and more. The mill is versatile, suitable for applications in chemical, pigment, powder coating, mineral, coal, food, sweet, cosmetic, and pharmaceutical industries. Additionally, it features a robust construction and is available as a pressure shock resistant version (PSR 11) for areas where explosive dusts might be present.
