Ball Mill Feed. With two equations and three unknowns, there are several solutions to equations [5] and [6], depending on the value attributed to the Fines Factor (Q1), each yielding different Corrected Ball Mill Feed Size Distributions (T'2). This is depicted in Figure 7. Figure 8 presents the variation of the corrected operating work indices with Q1. It shows clearly the sensitivity of the ...
Tailoring ball mill feed size distribution for the ...
This makes feed tailoring in ball milling an interesting parameter to investigate with the aim of maximising the desired mill product. To that end, batch tests were used to investigate the effect of feed tailoring in ball milling using a South African gold ore. Narrowsize feeds of the ore were prepared and milled with 20 and 30 mm sets of singlesize balls using the onesize fraction method ...
