### Feed Size VS Ball Size - Grinding Classification ...

One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum. Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill. A f80 = 6 mm would need a ball size of 75 mm. An empirical model from "Emerging Trends in Mineral Processing", 2005, is ...

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

Jun 01, 2018 Fig. 5 shows the variation of size class 1 (M1) with the milling time for the two feed size distributions. 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.

### Ball mill- factors influencing the size of product

Feed rate – With a high feed rate, less size reduction is effected since in this case the material is present in the mill for a shorter time. Properties of the feed material – with a hard material, a smaller size reduction is achieved. Weight of balls – With a heavy charge of balls, there is production of fine product. One can increase ...

### Calculate and Select Ball Mill Ball Size for Optimum Grinding

Apr 08, 2021 In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
