  • Grinding Mill LinersMineral Processing Metallurgy

    The metal lifter bar design is generally a function of the grinding application and mill size. The cross section however must retain two critical dimensions. The first is that the lips or edges of the lifter that extend over the rubber plates must be kept at a minimum of 25 mm to provide adequate clamping of the liner plates by the lifter. In SAG mill operation the grinding rate passes through a minimum at a "critical size" (Chapter 5) which represents material too large to be broken by the steel grinding media but has a low self-breakage rate. If the critical size material typically 25–50 mm is accumulated the mill energy efficiency will deteriorate and the mill feed
