Introduction to Air Classification
Air classifiers are preferred over fine screening in one or both of the following situations: 1) the rate is too high for fine screening; 2) the cut point is too fine for screening. Take for example an application in which calcium carbonate must be separated at 75 microns. A common round vibrating separator with a 200 mesh screen can make a ...
