Veyex nylon rollers at Gudai-Darri: reliability and load lessons for mine engineers
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Veyex has trialled heavy-duty nylon conveyor rollers at Rio Tinto’s Gudai-Darri iron ore mine in Western Australia, where previous high-density polyethylene (HDPE) rollers were failing prematurely under high-tension loads. The case study covered two specific conveyor applications, with the nylon rollers subjected to extreme belt tensions and impact loading typical of large-scale iron ore handling. Results showed markedly improved roller durability and reduced maintenance interventions, signalling potential lifecycle and reliability gains for high-load overland and plant conveyors in similar hard rock operations.
Technical Brief
- Heavy-duty nylon rollers were installed on two specific Gudai-Darri conveyors operating under extreme belt tensions.
- Previous HDPE rollers on these conveyors experienced premature structural failures when subjected to the same load regime.
- Trials were conducted in-situ at Rio Tinto’s Gudai-Darri iron ore mine in Western Australia.
Our Take
Rio Tinto’s Gudai-Darri iron ore operation in Western Australia sits in the same Pilbara export chain that will be competing with new high‑grade supply from Guinea’s Simandou, so higher‑reliability components like Veyex nylon rollers help protect throughput as margins tighten on standard Pilbara ores.
In our database, Rio Tinto features heavily across both iron ore and aluminium stories, from Gudai-Darri to the Tomago smelter power deal, signalling that incremental productivity gains at mines can have knock‑on benefits for its downstream processing and marketing portfolio.
