  • An overfilling indicator for wet overflow ball mills

    This is attributed to the fact that the slurry pool on the opposite side of the rising ball media would counter the torque required to rotate the mill shell and lift the ball media leading to a decreased mill power draw. Therefore unlike the AG/SAG mill the power draw data cannot be used as an indicator of overfilling for an overflow ball mill.
