Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.Effects of mill feed size on product fineness and energy,,This is expected as larger initial particle size requires greater energy for reaching the desired degree of milling. This observation is also corroborated by published studies on rod grinding and stirred bead milling that indicate that a finer initial size results in lesser energy requirement to achieve the targeted product particle size [18,25].EFFECT OF BALL SIZE DISTRIBUTION ON MILLING PARAMETERS,2.4 Effect of ball size 29 2.4.1 Empirical approaches 29 2.4.2 Probabilistic approaches 33 2.5 Abnormal breakage 36 2.6 Effect of ball mixture 37 2.6.1 Ball size distribution in tumbling mills 37 2.6.2 Milling performance of a ball size distribution 40 2.7 Summary 41 Chapter 3 Experimental equipment and programme 43Effect of feed size on residence time and energy,,01-02-2021· Impact of feed size on the change rates of class 2 and class 3.
