Gamma distribution, probability, distribution curves


The prediction of size distribution curves of jaw crushers product is one of the most important parameters in controlling its use. Experimental and analytical studies are carried out on cubic samples of marble and limestone. The study shows that the size distribution curves in crushing obey the Gamma distribution. Definite relationships are obtained between either average diameter of the product or standard deviation and the set of the jaw crusher (S). The experimental values of the parameters of Gamma distribution (act, Pact) are compared with the calculated ones obtained from the above relationships. It was found that the greater the set of the jaw crusher, the greater the deviation.
