Abstract. Nkwanyana and Loveday (2017) used batch grinding experiments in a 0.6 m diameter mill to test partial replacement of steel balls (37.5 mm) for secondary grinding, by partly rounded pebbles (19–75 mm) from a SAG mill. At the optimum pebble content of 25% by volume, a 25% saving in steel ball consumption and a 15% saving in energy ...

In Grinding selecting calculate the correct or optimum ball size that allows for the best and optimumideal 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 ...

To obtain the dissipated energy of particles, the motion of the particles and balls was simulated using DEM in a planetary ball mill under dry conditions (Hirosawa et al., 2019).We used an in-house DEM code for the simulation, that is based on the method proposed by Tsuji et al. (1992), and the Hertz-Mindlin contact model was used to estimate the contact force.

While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.Assessing load in ball mill using instrumented grinding,SM500 × 500 cement ball mill (a) The cement ball …
