A 10–20% Reduction in Grinding Cost Is an Engineering Problem. We've Already Solved It.

Cost Driver 1 — Wrong Specification A high-chrome ball in a low-abrasion application delivers high hardness you didn’t need and a higher unit price you didn’t have to pay. A forged ball in a high-abrasion application wears faster than specified. Getting the specification right is the single highest-leverage decision in grinding media procurement.

Cost Driver 2 — Premature Breakage The industry average breakage rate exceeds 2%. At 2% breakage, a 500-ton/month operation is absorbing 10+ tons of non-grinding media per month — media that’s consuming liner space, adding to scats, and generating zero comminution value. Our breakage rate is ≤0.5%. The cost-per-ton difference is immediate and measurable.

Cost Driver 3 — Supply Disruption A grinding media stockout at a remote operation is not a supplier problem — it’s your problem. An unplanned shutdown of even 24 hours in a Tier-1 operation can eliminate weeks of cost savings from better pricing. Supply reliability is as much a part of your cost structure as unit price.

Cost-per-ton (CPT) is the only metric that matters in grinding media evaluation. It integrates:

• Unit price($/ton of media)
• Wear rate(kg of media per ton of ore processed)
• Breakage rate(non-productive media consumption)
• Downtime contribution(media-related mill stoppages)
• Liner interaction(media-liner compatibility losses)

A supplier offering 10% lower unit price but 30% higher wear rate and 3% breakage is not cheaper — they’re more expensive. We model this explicitly for every client, and we benchmark against your current program to demonstrate the delta.
