May 01, 2014 The specific rates of breakage S i increases with the rise of the larger-size balls' proportion in ball size distribution, and S i can be determined by the mean contact force F mcf, formulated as S i = A 10 kF mcf, where the constant A is 0.437 and k is 0.0252. (3) Ball size distribution has a certain effect on grinding efficiency.

اقرأ أكثرcharge motion. It is well known that ball milling efficiency varies during the lifetime of the shell liner. For instance, the mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty.
