DAIRY PROCESS
Air Classifier Mill
Dairy plants use Air Classifier Mills for Ultra-Fine and Controlled Particle Size Grinding
Air Classifier Mills incorporates an internal air-classifying wheel with an independent drive giving precise control over “particle cut point” selection. Suitable for batch processing or continuous operation. This range of mills serves all industries producing fine powders where control of grinding temperature and particle size distribution are of primary importance.

PPS Air Classifier Mills are high energy grinding mills with an integral classifier to produce ultra-fine powders.
Features Include:
- High Energy Controlled Grinding
- Integral Classifier for a Finer Powder
- Tight Particle Size Distribution
- Large Range from 5hp to 400hp
- Easy Clean ‘Clam-Shell´ Body Option
Product Range
PPS Air Classifier Mills are available in a large range of sizes, from small lab pilot units through to 400 hp production units.
