Centrifugal type Closed Circuit Air Classifier is required to separate coarse and fine dry powder material from 60-350 mashes. The Closed Circuit Air Classifier can either remove coarser particles like free iron, their oxides, grit, silica, heavy impurities, or fine/light foreign material as to de-dust a product. The Closed Circuit Air Classifier comes with deflector blades that produce centrifugal force and air current to separate particles and impurities on weight basis. The Centrifugal type Closed Circuit Air Classifier is used to classify cement, flour, chemicals, pigments, food colours, minerals, sand, cement, etc.
