Air Classifier
Centrifugal type closed circuit VAC-40 Air Classifier is to separate coarse and fine dry powder material from 60-350 mashes. This machine is not grinding material but for getting uniform size of powder at out-let. It 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.
