Sturtevant air classifiers balance the physical principles of centrifugal force, drag force and gravity to generate a high-precision method of classifying particles according to size and density.
Whirlwind internal fan air classifier for fineness of 100 to 400 mesh. Side Draft external fan air classifier for fineness of 100 to 400 mesh. Superfine external fan air classifier for fineness of 44 to 5 microns. Classifiers process aggregates, ceramics, chemicals, fly ash, foods, minerals, metals, plastics, and other materials.
