how ball mill ore feed size affects tonnage capacity

Modifying blasting practices to achieve a more suitable mill feed size which varies according to the crushing/grinding circuit can achieve up to a 30% increase in throughput. Following an initial benchmarking of an operations practices, SRK can advise on how value-added blasting will deliver improvements in both mill capacity and ... The effect of increasing the feed size was found to be dependent upon the mode of mill operation ie AG or SAG, with AG mill throughput increasing as the feed F80 was increased.

maximum feed size for ball mill

The change from a SAG mill to an HPGR in primary grinding results in a lower overall power consumption the comminution circuit. In comparison to using staged crushing as ball mill feed prepara-tion, replacing the tertiary circuit with an HPGR frees up ball mill capacity (or reduces the size of the ball mills and grinding media consumption). Despite this, the variability of wi when performing the ball mill Bonds standard test is not always understood enough. This study shows the results of a variability analysis (a 33 factorial design) performed to elucidate the influence on wi of several parameters obtained from the particle size distribution (PSD) in feed and product.
