Roy Hill – ROM4 Mine Expansion


Roy Hill – ROM4 Mine Expansion

Project Type



Roy Hill Overland

Pilbara, Western Australia


Project Type Roy Hill Overland
Location Pilbara, Western Australia
Completion 2022

Project Scope

Roy Hill is a world-class iron ore operation located in Western Australia’s Pilbara region that delivers around 60 million tonnes per annum of iron ore.

As part of their ROM4 mine expansion, Roy Hill constructed a new overland conveyor system totaling over 8km in length. PROK was selected to manufacture and supply the idlers for the new system.

PROK was awarded the contract for the conveyor idlers off the back of a long history of success with various overland conveyor systems across the globe.

Roy Hill required the new overland conveyor to connect a new crusher to the existing mine infrastructure. The system comprises 2 overland conveyor systems approximately 8km in length.

The entire project scope for the conveyor components included the manufacture and supply of 23,500 rollers and 6,500 idler frames.

The majority of the rollers will be PROK HDPE, our market-leading, lightweight composite roller. PROK HDPE was chosen due to its lightweight construction and exceptional reliability. The rollers include dual-layer wear indicator technology which facilitates smarter roller maintenance.

Over 17,000 rollers are PROK HDPE, our market-leading, lightweight composite roller with dual layer wear indicator technology.

PROK HDPE is proven in heavy-duty iron ore applications and will assist to reduce maintenance costs, increase production and importantly improve safety outcomes.

We were thrilled to be able to partner with Roy Hill on this project and look forward to working closely with them to continue to optimise conveyor performance.
