Grinding Mill Power ScaleUp. ... Also, for a given value of mill filling (J) the load of rods in the mill will exceed that of balls in the ratio of the volume of rods to the volume of balls, that is, 1 – /1 – = Thus, the power to drive a rod mill, without a powder charge, will be given approximately by.
Mathematical models are presented which describe the power consumption in agitated ball mills in absence of grinding beads. In addition, tests with grinding beads filling were also performed, leading to scale‐up guidelines with respect to power consumption. Finally, the influence of size and material of grinding beads was investigated.
