The Moly-Cop NG SAG ball is Moly-Cop's new generation grinding ball, specifically designed for today's high impact SAG milling environments. Moly-Cop has developed an innovative manufacturing process that produces a ball with greater impact resistance and reduced spalling than a standard SAG ball.
Sizes: Moly-Cop manufactures Moly-Cop NG balls in nominal sizes from 4.0” to 6.25” in diameter which are used in SAG Mill mineral processing operations.
Chemistry: An individual chemical profile has been developed for each diameter ball to correspond with the requirements for heat treatment. Specific alloy additions are included to produce optimum physical properties. The chemistry of the balls is controlled through a close collaboration with our bar suppliers and robust internal quality systems.
Surface & Volumetric Hardness: Surface and cross-sectional hardness of the balls depends on the microstructure of the steel which is altered using carefully selected heat treatment variables specifically designed for each particular alloy. The Moly-Cop NG ball is designed for use in high impact SAG mills where spalling and breakage are more likely to occur.
Density: The theoretical apparent packing density of the balls in a ball charge is 282 lbs/cu-ft or 4,520 kg/m3.
