Ball Mill Circuit Design

Design of a plant for adanac moly corp to include sag and ball milling the hardness of each sample was measured in terms of sag power index spi for sag grinding and bond ball mill work index bwi for ball mill grinding a further measure the minnovex crusher index ci was also measured for use in the ceet program to determine sag

T80 refers to the sag product size in microns transferred to the ball mill circuit the design procedure chosen by davy used the spi and bond ball mill work index values to select the required specific energy for both the sag mill and the ball mill the other tests were used for comparison and to confirm the chosen result then since used
