SOLUTIONS BY MINERAL

Grinding media solutions by ore type

Ore hardness, abrasiveness, and mill conditions change media performance. We tailor alloy, size, ball charge, and technical support to each circuit.

MINERAL-BASED SOLUTIONS

Match grinding media to the ore

Address wear, breakage, energy use, and throughput with media selected for the ore and grinding stage.

MORE MINERALS

Other ores require site-specific media selection

For other ores, we select alloy, size, hardness, and ball charge after reviewing ore hardness, abrasiveness, feed size, target P80, and current media.
