ball mill ball wear projection. in any mill, the rate at which the weight of any ball decrease is directly proportional to its weight. in any mill, the rate at which the diameter of a ball decreases is directly proportional to its diameter. in any mill, the rate at which the surface of any ball decreases is proportional to its surface.
table of contentsdata on ball chargesball mill ball wear projectionrecapitulation of ball wear formulaspractical application of theoretical conclusions in the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity; then, since the velocity may be considered as constant for all the
analyzing the breakage function, you could see that the breakage rate increase more in the coarse and decrease in the fine ore proportionally, the increase is bigger than the decrease , and the main objective in sag grinding is to obtain the maximum throughput more than the fine product generation, the fine product generation is ball mill labor, finally if the ball mills has no problems then the t80 makes no problem.
mills with the rod mill and ball mill laboratory work indices. note, in figure. 1, that the rod mill product slope is less than 0.5 due to an extra amount of nes present being ﬁ ﬁ ner than 650 μm. these ﬁ nes proceed to the ball mill improving the ball mill efﬁ ciency. also, the plotted rod mill p80 value, as shown in figure 1, is 2900 μm.

kinross gold will proceed with the phase one expansion of its tasiast mine in mauritania, which is expected to increase mill throughput capacity from the current 8,000 metric tons per day mt/d to 12,000 mt/d, while significantly reducing tasiast’s operating costs and increasing production. preparations for phase one construction to install incremental crushing and grinding capacity to the
