Mikro® CC Air Classifier

Hosokawa’s Mikro® CC Air Classifier is an in-line fines classifier that can handle a wide range of materials in many size ranges making cut points between 3 ?m to 20 ?m possible using unique internal dispersion systems.

The Mikro® CC Air Classifier was originally developed for dedusting powder coatings, removing fines product below 5 µm; however, its effectiveness can be applied to other fine chemicals. Hosokawa’s Mikro® CC Air Classifier is an in-line classifier that can handle a wide range of materials in many size ranges making cut points between 5 µm and 100 µm possible. The unique internal dispersion of material allows for sharp particle distributions while maintaining high throughput. The compact design of the Mikro® Classifier allows for complete access to the interior to facilitate cleaning and product changeover. Typical applications include: powder coatings (epoxy or acrylate based); fluidized bed and drying processes; hot gas systems and minerals.

The Hosokawa Micron classifiers and cyclones are coordinated perfectly to match the Mikro ACM® Air Classifying Mill series. The classifiers can thus be integrated in-line into a grinding system or can be employed off-line as an independent classifying system.

Design & Options:

  • Available for Pilot (2 HP) to Production (50 HP) models
  • Suitable for off-line and in-line particle separation processes
  • Capable of processing up to 6,000 lbs/hour
  • Sharp cut points down to 3 µ
  • Intensive dispersing power
  • Controlled flow pattern
  • Simple to clean and maintain
  • Optional wear protected parts

The Mikro® Classifier is characterized by its optimized cyclone-classifier principle. Because of the optimized flow pattern and the use of a high-efficiency classifying wheel, the Mikro® Classifier is especially suitable for ultrafine classifying operations in in-line mode.


The feed product is fed tangentially to the top of the classifier. The classifying wheel separates the feed product into a coarse fraction and a fines fraction. The classifying air and the fines pass through the classifier wheel, whereas the coarse material settles on the housing wall. A flow of secondary air introduced tangentially above the product discharge recirculates any unclassified material to the classifying wheel for renewed classification, whereby agglomerates are dispersed and the material is then distributed uniformly in the classifying zone. The optimized classifying wheel geometry results in a high product yield at an extremely high precision of cut. In addition, the low pressure drops result in low energy consumption and correspondingly lower operating costs.

The Mikro® Classifier was designed for all types of fine to medium-fine products. It is especially suitable for powder coating classification aimed at reducing the ultrafine portion under 5 – 10 µm.
