Our heritage and relentless search for improvement is what sets us apart. From developing the first heat-treated grinding ball in the 1930s to releasing the Next Generation (NG) SAG ball in 2016, Molycop has a 100-year track record of innovation leading to increased productivity for customer mines all over the globe.

Grinding media costs in milling processes are significant – often 30–50% of the total milling cost. This paper highlights difficulties with Marked Ball Wear Test methodology for New Product Development processes. It proposes testing processes for better assessing grinding media products and accelerating grinding media product development.

Developing more durable materials for mill liners and grinding media is a significant trend. These types of product development will significantly change the operation of the SAG mill if they do not entirely replace it. Catalysts of change in the industry ahead The immediate future of the SAG mill is one of change. Most likely the changes will be:
