REBIO Mining Wear Parts Enter Bulk Supply at the Simandou Iron Ore Project

From a 152-day field trial processing 3.72 million tonnes of iron ore to contracted bulk supply, REBIO GROUP is bringing advanced ceramic/MMC mining wear parts and crusher wear solutions to one of the world’s most demanding hard-rock mining environments.

NANJING, China — October 1, 2026 — REBIO GROUP today announced that, after nearly a year of technical coordination, wear analysis, sample development, field validation and performance review, a new generation of high-performance mining wear parts promoted by REBIO GROUP together with its Chinese technology partner has moved from trial validation into contracted bulk supply for the Baowu-backed Simandou iron ore project in Guinea.

The first contracted scope covers 144 MMD1150 crushing-beam tooth-cap assemblies for high-impact, high-abrasion iron ore crushing. The technical agreement also includes a performance commitment of more than 2.5 million tonnes of raw ore per component and a full-capacity verification mechanism in which 18 parts are randomly selected for installation and field validation. The transition from sample testing to measurable contractual performance marks an important step for the technology as a mine-ready crusher wear parts solution rather than a laboratory material concept.

Ceramic/MMC Crusher Wear Parts Engineered for Hard-Rock Mining

The technical platform belongs to the ceramic-reinforced metal matrix composite, or ceramic/MMC wear parts, family. For the 1150 toothed-roll crusher tooth cap, the current technology route is positioned as a high-chromium ceramic thermal-composite bimetal system. The objective is not simply to make a harder wear-resistant part, but to engineer a complete wear system around ore abrasiveness, impact load, actual wear tracks and the maintenance window of the plant.

Depending on the application, the material architecture can use Al₂O₃, ZTA or TiC hard reinforcement phases for abrasion resistance, combined with high-chromium, high-manganese, martensitic or bimetal metal matrices that carry impact loads and help arrest crack propagation. Interface engineering can involve thermal bonding, preforms, metallurgical bonding or mechanical interlocking, with particular attention to wetting, residual stress and ceramic displacement.

The second part of the technology route is geometry redesign. Reinforcement zones are placed along the actual wear path instead of being distributed indiscriminately, while tooth profile, chamber geometry and mounting structure are optimized for the specific crusher and ore. The result is a mining wear solution evaluated by tonnes processed, productive operating hours, remaining wear thickness and cost per tonne — not by material hardness alone.

152-Day Field Trial: 3.72 Million Tonnes Processed with 85 mm Wear Layer Remaining

Field data became the decisive factor in moving the new crusher wear parts from trial to bulk procurement. According to the Technical Trial Report for New Wear-Resistant Tooth Caps for the Model 1150 Toothed-Roll Crusher, the product completed a 152-day field evaluation from March 21 to August 20, 2026.

By August 19, the new tooth caps had processed 3.7217 million tonnes of ore. From a designed wear thickness of 140 mm, measured wear was approximately 55 mm, leaving about 85 mm of usable wear layer — roughly 61% of the designed wear thickness still remaining. The report recorded stable, even wear with no abnormal cracking or detachment.

For comparison, the original standard tooth cap typically processed about 0.8 million tonnes. At the end of the current assessment, the new ceramic/MMC wear part had already processed about 4.65 times that benchmark while still retaining more than half of its designed wear layer. The design target for the new tooth cap is 5–8 million tonnes, equivalent to approximately 6.25–10 times the typical processing volume of the original standard part. The 5–8 million-tonne figure is a design target and remains subject to confirmation through the complete service cycle.

MMD Crusher Wear Parts Move from Trial to Contracted Bulk Supply

For large iron ore mining operations, the commercial value of longer wear life extends well beyond the price of a single component. Longer-lasting MMD crusher wear parts and roll crusher wear parts can reduce change-out frequency, planned and unplanned shutdowns, maintenance labor, safety exposure and emergency inventory requirements.

This is why REBIO evaluates mining wear parts through a cost-per-tonne model. Purchase price is only one variable; the more important calculation includes replacement labor, shutdown losses, spare-parts inventory, logistics lead time and production stability. A higher-performance wear component creates customer value only when it lowers the total operating cost of the crushing circuit.

From Crusher Tooth Caps to a Broader Mining Wear Parts Portfolio

“The most important meaning of the Simandou project is not simply that we received a bulk order. It is that a combined approach of advanced materials, structural redesign and field validation has been tested under real large-scale mining conditions. Testing of other wear-part categories at the Simandou project is continuing, and we will expand the cooperation steadily as each product generates reliable field data.” — Mr. Wu Jun, Head of CEP BU, REBIO GROUP

The same technology platform is now being extended beyond crusher tooth caps. Current and potential applications include MMD crushing-beam tooth-cap assemblies, crusher shaft crowns and tooth caps, cone crusher and HP-series liners, feeder wear liners, hopper liners, chute liners and other fixed-plant wear positions where abrasion, impact and downtime create a measurable operating cost.

REBIO’s approach is to begin with a high-pain wear position, establish a baseline, carry out field trials under comparable operating conditions, measure wear and tonnes processed, and only then expand into a wider mining wear parts portfolio. The goal is to move from supplying individual wear-resistant parts to delivering a repeatable wear management system.

Lower Cost per Tonne: The Customer Value of Longer Wear Life

The mining industry increasingly evaluates crusher wear parts and ceramic wear parts by campaign life and cost per tonne rather than by price per kilogram. For remote mines, this distinction is even more important because a premature wear-part failure can trigger emergency logistics, additional safety stock, maintenance mobilization and lost production.

The Simandou field data illustrates that shift. With 3.7217 million tonnes already processed during the 152-day assessment and approximately 85 mm of wear layer remaining, the value proposition is not simply ‘a harder part.’ It is fewer interventions, more predictable maintenance, higher crushing-circuit availability and a lower total cost for every tonne of iron ore processed.

REBIO Extends Its Mission-Critical Technology Strategy into Global Mining

“REBIO GROUP is positioned as a Mission-Critical Technology & Overseas Industrialization Partner. After serving global customers in solar and energy-storage power projects, unmanned transport platforms and IVD, we are applying the same model to mining: identify the technologies that materially affect customer uptime and lifecycle cost, then convert China’s proven materials, manufacturing, engineering and supply-chain capabilities into products that can perform reliably at overseas sites.” — Mr. Leo Jiang, Vice President, REBIO GROUP

“A wear part may look like a small component in a mine, but the premature failure of one critical crusher part can stop an entire production line. That is exactly what mission-critical means to us. Following the Simandou project, we intend to bring these validated ceramic/MMC mining wear solutions to more iron ore, copper and gold mining customers worldwide.” — Mr. Leo Jiang

For REBIO GROUP, the Simandou bulk procurement is not the end point of the mining wear parts program. It is the beginning of a broader model: start from a critical crusher wear part, validate it with field data, and then expand into crushing, feeding, storage and material-transfer systems with measurable performance targets.

The long-term objective is not to build another catalogue of aftermarket crusher parts. It is to deliver verified, application-specific mining wear solutions supported by material science, structural engineering, field data and long-term wear management.
