Centrifugal air classifiers offer effective fines

C entrifugal air classifiers are used extensively to process aggregates, foods, metals, chemicals, minerals, fly ash, ceramics and other materials. Air classifiers are used for dry processing; to effectively remove fine powders, the surface moisture of the feed must be very low. Air classifiers work effectively on granular coarse discharge with limited fines and dust, or product that is mostly

Factors Affecting Air Classifier Efficiency

It is also fairly well-known, that it is by far much more difficult to achieve high efficiency with dry classifying than with wet. Hence, it is highly desirable to create conditions for improving the dry air classifying methods, so that the high energy consumption associated with producing fine dry powders can be minimized.

Mechanism and Fine Coal Beneficiation of a Pulsating

ABSTRACTTraditional air classifiers produce binary splits based on the terminal velocity rather than the density of the feed. In this study, a pulsating air with a sine-like shape wave was introduced into a vertical column air classifier to achieve the density dominant separation on −6+3 mm fine coal. A lab-scale separation device was used to investigate the effects of pulsating
