MAC Air Classifier

The MAC forced vortex units process dry materials to an unmatched fineness and uniformity over a wide range of feed variations, either in closed-circuit with a conventional milling system or as independent “stand-alone” systems that incorporate feeder, fan and product collection equipment. This particular 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

Here are the following types of material that have been used in our air classifier (Keep in mind that there are more dry free flowing materials that can be easily processed in our air classifier are not be listed below):
