Balls

Molycop Worldwide

Molycop's network of manufacturing facilities, distribution centres and regional sales offices service over 400 mines across 40 countries.

High hardness for maximum abrasion

Molycop manufactures grinding balls to exacting internal specifications at its grinding media production facilities across the globe. Balls for use in ball milling operations are designed for maximum abrasion resistance using high carbon content and high hardness levels.

Specifications

Size – Molycop manufactures forged 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.

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 – Long-established strategic relationships with local and foreign raw material suppliers mean we can ensure all balls supplied to our customers are made from the highest quality products and meet strict Molycop specifications. This, combined with our global manufacturing network, gives our customers the confidence in our product that only Molycop can provide.

Digital mining: Leveraging the gold price

Molycop’s processing optimisation services are improving mining operations globally.

Behavioural zone identification in rotary mills

Dr Paul Shelley, VP Innovation at Molycop, has co-authored a paper for journal Minerals Engineering that shows how energy wastage in semi-autogenous grinding mills can be reduced.
