Air Classifier Mills


Our Air Classifier Mill offers fine grinding capability plus greater control over particle size distribution. Typically grinding to a particle size in the region of D97 = 10µm, our Air Classifier Mill serves all industries producing fine powders where control of grinding temperature and a narrow particle size distribution is of prime importance.


Particle size is controlled by fully adjustable rotor speed, classifier speed, airflow rate and feed rate. For operational efficiency, our mills are available with easy clean designs that include the fully opening “clam shell” body and several other options where process considerations demand easy access for inspection, cleaning and maintenance.


This feature is of particular benefit to multi product users who need quick product change over with no cross contamination.


All models available in carbon steel or stainless steel 304L or 316L.
