Kason introduced its CAM 1300 high capacity air classifier mill that combines impact grinding and air classification in a single machine. This air classifier mill can produce fine grinds with narrow particle size distribution in the range of D97 = 10µm typical at rates to 15 tonnes per hour for large-scale processes.
The mill allows control of the air flow rate and grinding temperature to condition heat-sensitive or hygroscopic materials.
Material enters the milling chamber where a spinning rotor impacts the particles against grinding segments inside of the chamber wall by centrifugal force. A rising column of air lifts the particles into the rotating classifier wheel, separating on-size material and directing it to the process air stream for collection or further processing.
Particle size is readily controlled by varying the rotor speed, classifier speed, airflow rate and feed rate, eliminating the need for separate classification equipment.
The easy-clean design provides complete interior access for change-outs of grinding media and sanitizing to prevent cross- contamination.
The CAM 1300 is available in carbon steel or in 304 or 316 stainless steel finished to industrial or sanitary standards. Hastelloy and other alloys are also available.
