effects of grinding media shapes on ball mill performance Core. Spherical grinding media are predominantly used in final stages of ore Considering that worn balls in an industrial mill charge constitute about 15 to 40. A discussion on the measurement of grinding media wear
This work focuses on investigating the impact of worn balls on milling kinetics and assesses whether the effect of worn balls on mill performance requires any action to maintain maximum mill productivity. In the study, two media shapes are considered: spherical and .
The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results. In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time.
SAG mills of over 40foot diameter have been constructed. Like the ball mill, the AG/SAG mill will have a critical rotation speed above which grinding . effects of grinding media shapes on ball mill WIReDSpace. grinding efficiency of milling is affected and it was therefore decided to conduct a thorough study of the impact of worn balls on grinding.

mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty. Figure 5 shows the evolution of the mill discharge product size in relation to the lifting effect of the liners.
The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
