PROK has been selected by Roy Hill to manufacture and supply the idlers for a new circa-8km overland conveyor system as part of the iron ore mine’s Rom4 expansion in Western Australia.

PROK says it 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 requires the new overland conveyor to connect a new crusher to the existing mine infrastructure. The system comprises two overland conveyor systems that are approximately 8 km 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, a lightweight composite roller. PROK HDPE was chosen due to its lightweight construction and exceptional reliability, PROK said. The rollers include dual-layer wear indicator technology which facilitates smarter roller maintenance.

PROK General Manager WA, Wade Guelfi, said PROK HDPE will bring a range of benefits to Roy Hill’s operations.

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