What is an Air Classifying Mill?

An Air Classifying Mill is a high-tech machine that combines grinding and air classification into one compact, efficient process. The mill works by conveying material through a grinding chamber, where high-speed rotors break down particle size by impact. Meanwhile there is an internal air particle separator which segregates the particles size wise which allows the finer particles to be removed and the larger or coarser particles to be recalculated back into the mill to continue the grinding. A consistent particle size is assured in the closed-circuit process that makes miller favorable where high precision is required such as chemicals, pharmaceuticals and even food processing. One special consideration to be given to the Air Classifying Mill employed to make the grinding of the heat-sensitive and the abrasive materials effectively.

Working Principle of Air Classifying Miller

  • Material Feeding: The raw material flows by feeding into a grinding chamber, usually with a pneumatic or a screw feeder, to achieve the homogeneity of flow into the high-speed rotor.
  • First-Stage Grinding: The particles are thrown against the grinding media and the rotor chamber walls as it bangs against the beam of impeller hammers, and is thus reduced to smaller sizes due to the impact and attrition.
  • Airflow Entrainment: At the same time, an induced airflow, usually provided by a blower or fan—conveys particles to the classifier, cools them, and avoids overheating.
  • Classification: Within the classifier, centrifugal force and air drag combine: finer particles remain suspended and pass through, whereas coarser particles are thrown back into the grinding zone to be reground.
  • Recirculation & Second-Stage Grinding: Course particles are recirculating back to the grinding zone—usually through a second stage grinding—until they become fine enough.
  • Product Collection: Ultrafine, classified material is conveyed through airflow to a cyclone or bag filter, where it is separated and collected as final product.
  • Control of Performance: Operators may control fineness by regulating rotor speed, classifier wheel speed, airflow, feed rate, and clearances inside—providing fine control of particle size distribution.

Types of Air Classifying Miller:

Explore the various types offered by our leading Air Classifying Mill Manufacturers in UAE, designed for precise particle size control across diverse industries.

  • MS Classifying Mill: This small, mild steel mill combines grinding and air classification within a single unit. It's suited for medium-scale production in chemical and food sectors with adjustable particle size without shutdowns. With 5–30 HP drive and capacity of 200–1,500 kg/hr, it optimizes efficiency and flexibility to meet diverse processing requirements.
  • 10 ACM Liner: Made of stainless steel and designed for industrial settings, this round mill processes as much as 10 TPH of material. With the aid of spin-on hammers and deflector liners, it guarantees uniform particle size and reduced wear. It's ideal for bulk operations requiring longevity, robust performance, and accurate flow control.
  • Centrifugal Air Classifier Mills: Centrifugal Air Classifier Mills employ a classifier wheel that rotates to classify particles by their size and weight. Larger particles are flung outward by centrifugal action and recirculate for additional grinding, while smaller particles are swept up in the airflow. Fine particles are swept with airflow; coarse ones are recirculating for regrinding. Suitable for chemicals, minerals, and pharmaceuticals with exact size control.
  • Static Air Classifier Mills: Static air classifier mills have a stationary classifier and airflow to sort particles by size. Fines exit through the classifier, and coarser particles get recycled back for grinding. Perfect for food and pharma industries, particularly with heat-sensitive applications.
  • Hybrid Air Classifier Mills: Hybrid mills utilize rotating and static classifiers to improve particle size control. Dual-action design provides greater classification efficiency and uniformity. Typical in fine chemical and high-tech material processing.
  • Pin Mill Classifiers: Pin mill classifiers employ rotating pins or spikes to shatter materials with high shear. Fine particles are removed by air, while coarse particles are ground again. Ideal for spices, sugar, and low-contamination, food-grade uses.
  • Hammer Mill Classifiers: Hammer mill classifiers employ high-speed hammers or blades for grinding and air classifying. Hammer mill classifiers are effective to grind hard materials and have variable particle sizes. Finds broad application in recycling, agriculture, and chemical processing.
