Classifier Milling Systems manufactures high-efficiency cyclones in various constructions, including special alloys and refractory-lined cyclones, designed to meet extreme and challenging work conditions, such as work environments associated with high temperatures or corrosive gases. CMS has installed cyclone classifiers for dry powder processing and separation of powder coatings, pigments, resins, bauxite, gypsum, limestone, cement, and numerous other feed materials.

How Do Cyclones & Cyclone Classifiers Work?

Airflow enters the cyclone’s inlet spiral flowing material at and below the cut point (via vanes of the rotating classifier wheel) while recirculating the coarse material for further grinding and separation. The cut point setting of the classifier wheel regulates the separation point of fine and coarse material. Dust (-2 µm generally) will discharge through an upper outlet duct to a dust collector. Classifier Milling System cyclones enable the operator to dial in cut points to as low as 10 µm.

Cyclone & Cyclone Classifiers from Classifier Milling Systems

  • Available in stainless steel and carbon steel construction
  • CMS offers a specialized heavy-walled grinding mill construction for high-pressure production, or combinations of high pressure and extreme temperature, or abrasiveness. Also available with PSR 11 (pressure shock resistant)
  • The cyclone body is one-piece welded construction (internal welds ground smooth)
  • Easy cleaning (extended acceleration inlet tube)
  • Access through the top (once the outlet tubing and exhaust is removed)

How it works:

Airflow enters the cyclone’s inlet spiral, directing fine material through the vanes of the rotating classifier wheel while recirculating the coarse material for further grinding and separation. The cut point setting of the classifier wheel regulates the separation between fine and coarse material, while dust materials will discharge through an upper outlet duct to a dust collector. CMS Cyclones enable the operator to dial in cut points as low as 10 µm d50.
