ball-mills and large-scale tumbling media mills, has been reported in a series of papers by Klimpel.9-12 By using the net production rate of material less than some specified screen size as a measure of grinding efficiency, along with the analysis of S and B values, it was found that there was a consistent pattern of change in break-

Generally, filling the mill by balls must not exceed 3035 of its volume. The productivity of ball mills depends on the drum diameter and the relation of drum diameter and length. The optimum ratio between length L and diameter D, L D, is usually accepted in the range 1.561.64.

Jun 01, 2018 In order to achieve this, the A.R tool employs a graphical technique that is defined by a set of pre-set conditions. In this investigation, the input variables were the ball and particle size distributions while the output variables were the desired PSD. The objective function was to maximize material in the specified intermediate size class. 2.
