HEAVY ENGINEERING AND WEAR PARTS
crusher stability and downstream mill performance. Wear life was extended by 17 %, reducing total cost of ownership and eliminating unscheduled shutdowns.”
The new design was adopted as standard for future orders, the company reports.
Phase Two chamber redesign is underway to drive additional gains in wear life and grind control, it added.

Key design elements included a uniform conical wear surface and matched initial CSS of 152 mm throughout the hydraulic travel range, ensuring seamless transition between the two mantles.
This saw a Ø110” mantle already on site re‐machined to the new conical profile with Ø108”, allowing installation within weeks. After the first mantle’ s full life, the larger‐diameter Ø109” version was installed to validate repeatability.
ME Elecmetal also conducted on‐site 3D scans and tracked hydraulic cylinder travel, confirming uniform wear and controlled CSS throughout both campaigns. Each mantle processed around 23.5 Mt with no unplanned maintenance, matching or exceeding previous campaigns while delivering a finer, more consistent P80. The plant also realised higher, steadier SAG throughput and avoided mill grind excursions tied to crusher performance.
The company explained:“ The optimised conical mantle design significantly improved
CMS Cepcor’ s global pursuit
CMS Cepcor closed a banner year by opening a facility in Perth, Western Australia, but this was just one of several major milestones it achieved in 2024.
In January 2024, after several years of serving the region, the supplier launched CMS Chile SPA.
“ We have a small, dedicated team working from Santiago,” Group CEO, Matthew Weare, said. The subsidiary was viewed as the next progression of the business, to have its own operating location so it could better serve the mining market with a Chile-based group company and local staff, he added.
Offering sales and engineering support, as well as parts, the subsidiary gives the group“ a more substantial base to support the Chilean and surrounding South American markets”, CMS Cepcor said.“ The business has been well received by many customers
