AMIT 135: Lesson 7 Ball Mills & Circuits – Mining Mill ...

Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., d↓V = 0.40 K√F dB = ball size (cm) F = feed size (cm)

Understanding the influence of HPGR on PGM flotation behavior ...

Oct 01, 2011 · The HPGR causes inter particle breakage while the ball mill has a combination of impact and abrasion breakage as the ore moves in tumbling motion. The steeper particle size distribution of the ball mill product is due to low fines, and low coarse particle content with the majority of the mass contained in the optimal size range for flotation.

size fraction for TS and CGR applications are shown in Table 1. The third column indicates the mass fraction of the total feed that is suitable for flotation in the HydroFloat. The HydroFloat flotation recoveries by size for the major pay-metals are illustrated as Figure 2 while the overall HydroFloat metal recoveries are shown in Table 2.

Effect of ball and feed particle size distribution on the ...

Jun 01, 2018 · Fig. 8 shows that the small 10 mm ball size is superior in generating more material in the fines size class, from both feed sizes used. If an objective function was to maximize the production of fines e.g. in the cement industry, the A.R shows that use of smaller ball sizes would give superior results.
