  • Mill Steel Charge Volume Calculation

    We can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media. 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. The loading or change volume can then be read off the graph below or

  • Optimum choice of the makeup ball sizes for maximum

    Abstract A grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the makeup ball sizes in tumbling ball mills. It was found that the optimum composition depends on various factors, including the feed size, the product size, the mill diameter and the breakage parameters. In all cases, binary mixtures of two ball sizes 50.8 mm and 25.4 mm

  • How to Eliminate Electrostatic Charging of Powder

    Powder processing operations can generate vast quantities of electrostatic charge via the movement of powder. The standard method of charging on powder processing operations is due to triboelectrifi ion, which is basically the contact and separation of the powder with processing equipment, the powder itself, or other factors that can cause charging, like surface contaminants.

  • Grinding Media Charge Motion inside Mill

    Theory of Von SteigerCascading MotionTheory of Davis aracting MotionThe first important modifi ion to the above treatment was suggested by von Steiger who pointed out that the hypothesis of free flight of the particle along the ascending branch of the parabolic trajectory is invalid since the continuous projection of material along any trajectory results in contact between the particles. Thus for the ascending branch of the parabola the speed along the arc is constant not variable as is the case with free flight of particles. On referring to Fig. 2.9, it is seen that the intrinsic equation to
