Seven banana screens (across three models), five diverging pan feeders and one grizzly feeder make up the scope of supply for the contract.

Highlighting the company’s international capabilities, the project will see all design completed at the vibrating equipment design centre in Sydney (Australia) manufacture and testing in the company’s Chinese plant, custom-made screen panels from the South African production facility and commissioning by the aftermarket services team in Chile. The project is being managed and co-ordinated by the Australian-based project management team.

The screens include a number of mechanical and operational improvements developed on a prototype vibrating screen now undergoing site testing at an iron ore mine in Western Australia.

The five larger screens feature laminated side plates to maintain structural integrity and reduce stress concentrations associated with the projected process tonnages. Additionally, machined transition flanges are welded in low stress area to the cross beams to actively reduce fatigue, and a unique spring removal system has been fitted to facilitate and reduce downtime during spring change-outs.

The six feeders have been designed to account for site conditions. A more robust deign, they are also equipped with exchangeable liners and an upgraded transition hopper to improve operational availability and performance.

Each of the vibrating feeders and screens for Mina Justa is equipped with CONiQ, the company’s proprietary continuous six-dimension condition monitoring system, to track and alert operators to abnormal operating conditions. Feeder control systems have been electronically aligned with the screen’s installation.

“This is a truly international project and from our point of view it is the best way to give our customer the equipment that will deliver higher process efficiency and longer service life,” said project manager Lauren Williams.

“Although based on standardised platform designs for screens and feeders, each unit has been subject to a customising process to meet site and processing capacity requirements,” Williams said. “We are delivering an integrated package of screens and feeders to optimise availability and productivity and represent the best value for money.”
