Air Classifier Mill Grinding System

The PPS Air Classifier Mill is a vertical grinding mill incorporating an internal air classifying wheel with an independent drive. Product is fed into the grinding chamber by either a feed screw or a pneumatic conveying system via a rotary feed valve.An air classifier mill combines a mechanical impact mill with a dynamic air classifier. Ideal for large-vol- ume continuous processing, the mill is one of today's most widely used grinding machines for reducing dry fine chemicals, food products, and other materi- als.Classifier mills combine a grinding/milling system with a particle size classifier which continuously recirculates over-sized particles back into the grinding zone. The classifying action ensures a uniform final product with a narrow particle size distribution.
