Air Classifying Mill operates on the principle of impact grinding and employs high rotor speeds with a striking edge velocity of up to 120 m/s. Size reduction takes place by the impact of material particles on the rotating grinding surfaces (hammers or
pins) and on the fixed liner or grinding track. Air Classifier Mills are designed for producing micro-fine particle size. High air, unique multi teeth rotor and serrated liners fitted in the air classifier mills create numerous
air whirls, turbulence and progressive grinding.
The air classifier mills are designed to control the top cut size, great turbulence, and high air whirls to ensure minimum temperature increase to handle heat sensitive materials. The classifier retains coarser particles while suction fan discharges fine powder through cyclone separators and dust is collected in filter bag units. All air classifier mills are supplied with pneumatic conveying system.
