### SAG/AG SCU Millwatch

Maintaining an optimum charge in a SAG mill remains one of the fundamentals for efficient mill processing. If the charge level or the ball to charge ratio is incorrect, breaking liners and/or increasing power consumption is inevitable and can only result in degraded mill efficiency. To minimize reline time, it is critical to set the charge height at an optimum level.
