Grinding Balls

Moly-Cop Grinding Media

Moly-Cop Grind Media Overview
 

Designed for maximum abrasion resistance

Moly-Cop manufactures grinding balls to exacting internal specifications at its grinding media production facility across the globe. The balls are manufactured from high carbon, alloy steel bars and then forged into balls. Balls for use in mineral processing ball milling operations are designed for maximum abrasion resistance using high carbon content and high hardness levels.

Product Specification

Sizes: Moly-Cop manufactures grinding balls for use in ball milling and regrind applications in nominal sizes from 1.0” to 4.0” in diameter. 

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. 

Supply and Quality Guarantee

Long established strategic relationships with local and foreign raw material suppliers allow us to ensure all balls supplied to our customers are made from the highest quality products and meet strict Moly-Cop specifications. This combined with our global manufacturing network gives our customers the confidence in the quality of the product that only Moly-Cop is able to assure.

Engineered with optimum hardness for superior wear

The Moly-Cop XTH SAG ball has been specifically engineered with optimum hardness levels to deliver superior wear resistance and premium milling performance, particularly in higher impact mill environments.

Product Specifications

Sizes: Moly-Cop manufactures Moly-Cop XTH SAG balls in nominal sizes from 4.0” to 5.5” 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 XTH SAG Ball is designed for use in higher impact milling environments 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.

Supply and Quality Guarantee

Long established strategic relationships with local and foreign raw material suppliers allow us to ensure all balls supplied to our customers are made from the highest quality products and meet strict Moly-Cop specifications.

Greater impact resistance and reduced spalling

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.  

Product Specifications

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.
