It operates with very low temperature rise and is particularly well suited for heat sensitive materials. Five sizes are available, from a mini lab system to 200 H.P. Complete classifier mill systems can be provided. Units are also available in stainless steel. Prater Rota-Sieve yields at least six times the throughput capacity of a conventional screen with comparable screen area. Used for centrifugal scalping or sifting of powders and granular materials.
Operation is quiet, free of dust and vibration.
Quick and easy maintenance. Air Classifier Based on a highly successful air separation technique developed in Europe, the Air Classifier is used for accurate, high capacity separation of fine particles. Operates economically at cut points from 100 mesh down to as little as one micron. Available in several sizes from lab units to very large production sizes. An open-ended version that collects fines internally.
