MAC Air Classifier

Request a Quote

The MAC Air Classifier forced vortex unit processes dry materials to an unmatched fineness and uniformity over a wide range of feed variations, either in closed-circuits with a conventional milling system or as independent “stand-alone” systems that incorporate a feeder, fan and product collection equipment. This MAC air classifier works best on crystalline products that are dry and have a narrow distribution, preferably minus 50 micron or better. The MAC can be installed within existing air systems with very little modification necessary. Available in many sizes and in either mild or stainless steel, the MAC units can also include convenient optional equipment such as ceramic rotors and abrasion-resistant steel, rubber, polyurethane or ceramic linings.

  • Separates dry free-flowing product from 150 – 1 micron
  • Allows for very narrow particle distribution
  • Control of mean particle size & cut point
  • Pre-classification with cyclonic air stream
  • Adjustable secondary air system for precise cuts
