Praters Air Classifying Mills operates by using the combination of two stage closed circuit grinding/milling with an interstage air classifier all in one convenient unit. The internal air classifier continuously recirculates particles that are larger than desired back into the grinding zone ensuring an optimal final product particle size.
The CLM Air Classifying Mill offers the combination of two stage closed circuit grinding mill with internal air classification, all in one efficient unit. The unique capabilities of the CLM Air Classifying Mill out performs single stage air classifier mills when handling difficult to grind products and those products requiring a narrow particle ...
An Air Classifier Mill is used for milling and grinding heat sensitive material and provides precise control over particle cut point selection, by incorporating an internal air classifying wheel and an independent drive. Suitable for batch processing or continuous operation, the PPS Air Classifier range of Mills serve all industries that ...
The air classifier mill uses air to carry the product through the fine grinding milling machine and classifying process. The feed material is conveyed through the pneumatic feed duct into the grinding zone. The main airflow enters the mill through the main air inlet underneath the grinding disc which rotates with tip speeds of 70 to 120 m/s.
Grinding and Classifying are essential size reduction processes. The CMS Air Classifier Mill Grinding Zone configuration positions Impact Hammers mounted at the periphery of the Rotor Plate , a reversible Multiple Deflector Liner enclosing the Rotor Plate, Hammers and a Deflector Assembly located above the Impact Rotor. The space between the Classifier Wheel and Deflector Assembly forms the Classification Zone.

Air drawn into the mill via the Air Inlet entrains the feed material into an upward flow from below the Rotor Plate, dispersing the feed material to the Grinding Zone, where rotating Impact Hammers deliver high speed impact, shattering and deflecting particles to the Liner and back to the Hammers. Size reduced particles flow to the Deflector Assembly, which then diverts material to the Classification Zone. Fine particles below the selected cut pointwill pass through the vanes of the Classifier Wheel to the product and air outlet, while coarse particles above the cut point will return to the Grinding Zone for further reduction.
First and foremost, reliability. Our air classifier mills are rugged, high performance machines that will deliver superior final products at peak operational efficiency. Other benefitsinclude: 1. Durability. Long life. 2. High volume throughput on a single mill pass 3. Consistent particle size fineness down to 5 µm on steep distribution curves 4. Unrivaled energy efficiency 5. Easy to maintain, clean, and operate 6. Versatility over a wide range of materials lt;4 Mohs 7. Embedded proprietary technologies With solid steel construction, the grinding/classification chambers are rugged and long lasting. Internal components and wear parts are available in Stainless Steel, Abrasive Resistant materials, Hardened Refractory metals, and Ceramic. For added safety, all mills above 5HP include a lid lift.
