a ball mill shown in the above diagram is fed with fresh feed f as 30000kg h and the product p is screened using a screen of 295

Jan 01, 2016 Substituting n = −1.5 in Equation and integrating between feed particle size, F, and product particle size, P, yields Bond’s general expression for the energy required in size reduction as (3.2) E = 2 k 1 P − 1 F where k is a constant and a function of ore characteristics

    The gravity-induced low speed stirred milling technology, commonly referred to as tower mills, are widely used for fine grinding due to their high energy efficiency compared to conventional tumbling mills. Moreover, the lower operating cost, shorter installation period and simpler operating strategy make it attractive for many mines. Researchers have attempted to develop an ore
