The P.A.S. mill-classifier combines the following processes in a single step:

  • Impact and attrition grinding
  • Simultaneous drying
  • Dual classification (static + dynamic)
  • Independent settings

Result: a fine, consistent and continuous output, with a controlled particle size down to 7 µm (d99) and industrial-scale capacity depending on the application.

AIR-CLASSIFIER MILL

Benefits

Simultaneous grinding-drying process:

the energy produced by grinding is reused to dry the product

Consistent production for high fineness:

Excellent cutting precision, very narrow particle size distributions

Simplified temperature and particle size control:

Combined with a classifier or sifter, the attrition mill can handle a wide range of products, especially heat-sensitive ones. For this purpose, the equipment can be cooled by ambient air or cooled air.

AIR-CLASSIFIER MILL

Operating principle

The P.A.S. air classifier-grinder processes a wide range of products down to a fineness of 99% to 10µm. The P.A.S. features an integrated grinding plate and dynamic classifier, driven independently by motors controlled by frequency inverters. The P.A.S is available in several versions, allowing great flexibility of installation and use. A wide choice of grinding tools (platen, liner), combined with a static classifier and a dynamic variable-speed classifier, guarantees the quality of very fine, perfectly calibrated products, whatever the application. As an option, the P.A.S. can be equipped with our latest patented technological advances: latest-generation SEALMAX© classifier, OPTICYCLE© internal ultra-fine recycling system.
