New performance standards in dry classification below 10 microns at high feed rates are claimed for the new Majac Acu‐Cut classifier system, now being introduced on the European market. A patented high energy air concept is used to disperse thoroughly and then classify fine powders into coarse and fine fractions with cut size selectivity covering the entire sub‐sieve range from 0·5 to 50 microns. The manufacturers state that it is now possible to produce grit‐free powders below 5 microns in a dry process at production throughput rates or to pull out a specific size range anywhere within the particle size distribution range.
