The feed rate of the air classifier is in range between 2 and 6 kg/h, which is the function of bulk density. Rotor speed varies between 2500 and 15,000 rpm and air flow rate is in range between 5 and 30 m 3 /h. The target size of the classification can be adjusted with the air flow rate and rotor speed. Fig. 2 illustrates the internal structure ...

Air classifiers can be used as a single sizing device in an open circuit where the feed is split into fine and coarse products. These classifiers can also be used in a closed circuit with grinding equipment such as ball mills, rod mills, stirred mills, roller mills, hammer mills, vibration mills or jet mills.

Particles below a certain size and density are carried away with the water-flow, whereas the coarser and heavier particles settle. Basically the different wet classifiers are gravity settling tank, cone classifier, double cone classifier, hydrocyclone classifier, spiral classifier, and rake classifier. Gravity settling tank is the simplest type ...
