Product Description
Product Description
Grinding media represents a large portion of the total grinding cost and has a significant impact on mining OPEX. Selecting proper grinding media with the best quality is the key to improving grinding efficiency and minimizing downtime.
Whether you operate a ball mill or SAG mill, regardless of the wet or dry grinding environment, we can all select the most suitable grinding ball for you as per your specific application. 20+years of professional experience and advanced technology enable us to manufacture grinding balls with ultimate strength and toughness according to different material formulations.
All FOCREA balls have been tempered to maximize their mechanical properties. FOCREA balls are high-hardness from surface to the center, unbreakable, have no deformation, good for fine grinding and impact grinding.
