Air classifier mill PPS
for heat-sensitive and specialty powders
Kemutec‘s PPS air classifier mill is ideally suited for grinding ultra-fine powders, as well as heat sensitive powders. This type of air classifying milling machine is widely used in the food, nutraceutical, and pharmaceutical industries.
Moreover, precise control over the “particle cut point” is achieved through an internal air-classifying wheel and an independent drive, while typical milled particle sizes reach a D50 as low as 5 to 10 µm.
Consequently, these mills produce ultra-fine, consistent powders with minimal heat generation. For example, they are ideal for spices, grains and gluten-free flours, sugar refining, cocoa processing, plant-based proteins, nutraceuticals, and botanical ingredients. As a result, their precise classification ensures superior product quality, improved flavor retention, and reliable particle-size control for demanding food applications.
