The product from the SAG mill is fed to the ball mill, with the product from the ball mills being classified in cyclones. The underflow from the cyclones is recycled, with the overflow forming the feed to the flotation circuit. The milling circuit has a feed rate of 1500 t / hr. Consider two size classes, above and below 75 microns.

For example, a feed rate of 20 IPM means your machine advances 20 inches along the x- and y-axis in the course of one minute, regardless of how fast your bit is rotating. Feed rate does not impact your z-axis. Z-axis movements are determined by plunge rate (inches) and depth per pass.
The term "feeds" refers to the feed rate or the relative linear speed between the tool and the workpiece. For example, for drilling, it is the speed at which the drill bit travels down into the workpiece material. The equation for the feed rate is: small f = Ntimes C_mat {L}times n_mat {t} f = N × C L × nt.
program. At the time of this research, mill ball charged, feed rate, and average moisture were 7 tons (ball size was 100 mm) per week, 720 t/h and 5%, respectively. Then, ball abrasion rate was calculated by Equations 4, 5 and 6. Total mill feed per week = 720*24*7*0.95= 114912 tons (4) Total ball charge per week = 7*106 g (5)

For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower.
