This company’s PPS air-classifier mill (photo) incorporates an internal air-classifying wheel with an independent drive, enabling precise control over particle cut-point selection. Suitable for batch processing or continuous operation, this range of mills serves all applications that produce fine powders, where control of grinding temperature and particle-size distribution are of prime importance. PPS mills are available with fully opening clamshell body designs, enabling easy access for rapid product changeover, inspection, cleaning and maintenance. The PPS mill offers high-energy controlled grinding and its integral classifier yields finer powders with a narrow particle-size distribution. — Kemutec, Part of Schenck Process Group, Bristol, Pa.
