Air Separators | Air Classifiers | Williams Crusher

Air classifiers separate materials based on shape, size, and density and are most commonly used in an industrial process involving mixed materials that need to be separated quickly. For example, in recycling centers, an air classifier can sort through metal, paper, and plastics that arrive mixed together.

Air classifier - Wikipedia

An air classifier is an industrial machine which separates materials by a combination of size, shape, and density.. It works by injecting the material stream to be sorted into a chamber which contains a column of rising air.Inside the separation chamber, air drag on the objects supplies an upward force which counteracts the force of gravity and lifts the material to be sorted up into the air.

The CMS Air Swept Classifier Mill System combines dynamic-impact grinding and particle size classification in a single continuous process. Independent drives for the Impact Rotor and Classifier Wheel allow the system operator to independently adjust their rotational speeds, thereby optimizing drag and tip speed control in producing the desired particle size distribution.

Review of Global Gypsum Conference & Exhibition 2006

The design of the mill reflects the fact that syn-gyp is often supplied to the wallboard plant at a grain size less than that of the ground stucco derived from natural gypsum. The mill in fact features an internal disagglomerator and classifier, which allows recirculation and ensures the required retention time and full calcination of the gypsum.
