Based on studies conducted by Hukki, there is evidence to show that the Hukki classifier might well be an excellent classifier for dry coal grinding applications. In fact, the classifier is presently being used in an industrial coal grinding circuit in Finland. In light of these recent developments, the present program was initiated, the objective being to evaluate the Hukki centrifugal classifier as a classifier for fine coal. Under this program, the classifier will first be evaluated in the stand alone (open circuit) condition using an air-swept ball mill to prepare the classifier feed. This will be done to study the effect of feed rate, feed size consist, fluid/solid ratio and adjustable settings of the classifier on overall classifier performance. Then, comparative, closed circuit testing of the Hukki, twin cone and vari-mesh classifiers will be conducted utilizing the air-swept ball mill as the comminutor. The test work will be evaluated based on size selectivity and the reduction of specific grinding energy.
