• The iBolt The Intelligent Bolt for SAG Mill Relines

    Achieve. Greater Mill Efficiency. The Intelligent Mill Liner Bolt. Up until now SAG mill operations have lacked the means to intelligently determine mill liner replacements other than the "blind" option of shutting down production clearing the feed chute and doing a full physical inspection of the mill lining and its wear depth.
