Air Swept Classifier Mill System How it Works Benefits

The CMS Air Swept Classifier Mill System combines dynamic-impact grinding and particle size classification in a single continuous process. Independent drives for the Impact Rotor and Classifier Wheel allow the system operator to independently adjust their rotational speeds, thereby optimizing drag and tip speed control in producing the desired particle size distribution.
