ball consumption in sag mill

  • SAG/AG SCUMillwatch

    CHARGE LEVEL. 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.

    That is the SAG mill produces about 10.76 more than the ball mill in the final product. The average consumed energy at SAG and ball mills to produce one ton of final product was 23.16 kWh/t and 36.05 kWh/t respectively. Thus the ball mill consumes 12.89 kWh/t more energy than the SAG mill in producing the final product.
