• Effect of Slurry Solids Concentration and Ball Loading on ...

    flow through the mill is fundamental in trying to improve the efficiency of wet milling circuits. For a given set of operating conditions, the flow behaviour of slurry within the mill determines the slurry residence time inside the mill and consequently the holdup volume, both of which have a large influence on the milling efficiency.

  • Ball mill Wikipedia

    A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

    modelling of axial flow in ball mills (Cleary, 2006, 2009b). Prediction of slurry flow in a mill is a particularly difficult computational challenge. The rotating mill geometry and the requirement to resolve the free surfaces of the fluid make solution using grid based Eulerian flow solvers problematic. In particular, the fragmenting

    By using this approach, the mill can better measure the amount of slurry going to the various processes, helping to optimize the operation. Raw ore is fed to the ball crusher using mechanical transport methods, but from the ball crusher stage onward, water transportation is used to carry the ore throughout the rest of the processing steps.

As the flow transfers upwards, the ore slurry passes through the rotating discs and the free space between the static counter discs lining the wall (see Fig. 2).
