Air classifier mill for ultra-fine powder grinding
Optimize your milling operations with precision particle size control and temperature stability, enhancing product quality and uniformity for applications demanding ultra-fine powders.

Achieves Ultra-Fine Grinding and Precise Particle Classification
The PPS Air Classifier Mill from Kemutec is engineered for precise ultra-fine milling and controlled particle size distribution, making it indispensable for food, pharmaceutical, and chemical processing industries. This mill incorporates an internal air-classifying wheel with an independent drive, enabling fine-tuned particle cut point selection. Suitable for both batch and continuous operations, it excels in processing temperature-sensitive materials where tight control over distribution is crucial. The clamshell design enables easy access for rapid cleaning and maintenance, minimizing downtime. With models ranging from lab-scale units to 400 hp production mills, it offers a wide processing capacity ideal for applications like confectioners sugar and pharmaceutical-grade APIs. Customizable features such as temperature-controlled grinding, cryogenic milling, and explosion protection systems ensure integration into any production line setup, while maintaining compliance with industry standards.
