The Mikro® Acucut Air Classifier is a forced vortex air classifier designed to disperse, and then classify fine particles into coarse and fine fractions. High energy dispersing air enters the rotor radially around the entire outer edge. Feed material enters this dispersion air zone through an inlet in the rotor ring. Particles are acted upon by centrifugal and drag forces. Air carries the dispersed fines inward to the central fractions outlet, coarse particles move outward to the rotor periphery. Cut points are adjusted by airflow, rotor speed or both. The C-24 Air Classifier is capable of fine cut points down to 10 µm at rates up to 1,200 lbs/hour.
