large diameter ball grinding

  • Optimum choice of the make up ball sizes for maximum throughput .

    1 shows the typical variation of the S values with particle size xi for a given ball diameter. It can be seen that the S values increase with size, but reach a maximum and then decrease as the particles become too large to be broken efficiently by the grinding media. This relationship can be fitted empirically to an equation.
