How an Air Classifier Mill Works
The working principle of an pulverizer is based on impact, shear, and collision forces generated by high-speed rotating components. Key mechanisms include:
High-Speed Rotor & Blades: A motor-driven rotor with multiple blades rotates at extremely high speeds, creating intense turbulence.
Grinding Chamber: Raw material is fed into the chamber, where it is subjected to repeated impact between the blades, liner, and other particles.
Cyclone Separator & Dust Collector: After grinding, fine powder is separated by airflow, collected via a cyclone, and filtered to ensure no dust leakage.
Cooling System: Many models include water cooling or air cooling to prevent heat-sensitive materials from degrading.
The result is a consistent, ultra-fine powder with adjustable fineness, often ranging from 10 to 500 microns depending on the model and material.
Suitable Raw Materials for Air Classifier Mill
Ultra-fine pulverizers are versatile and can process a wide variety of dry materials, including but not limited to:
Note: Materials should be dry (moisture content typically below 5%) and not excessively oily or sticky unless specially adapted models are used.
| Category | Example Materials |
| Chemicals | Pigments, resins, carbon black, insecticides, fertilizers |
| Pharmaceuticals | Herbs, active pharmaceutical ingredients (APIs), excipients |
| Food & Spices | Sugar, starch, cocoa, chili, turmeric, coffee beans |
