Schenck Process has won a contract to design manufacture, supply and commission vibrating screens and feeders for the greenfield Mina Justa copper project, in Peru.
The order will see Schenck business units on four continents combine to deliver seven banana screens (across three models), five diverging pan feeders and one grizzly feeder.
Mina Justa, owned by Minsur and Empresas Copec through holding company Cumbres Andinas, is slated to produce around 100,000 t/y of copper when fully ramped up.
The screens and feeder contract will see all design completed at Schenck’s vibrating equipment design centre in Sydney, Australia, manufacture and testing in the company’s Chinese plant, custom-made screen panels from the South Africa production facility and commissioning by the aftermarket services team in Chile. The project is being managed and coordinated by the Australia-based Project Management team, Schenck said.
The screens include several mechanical and operational improvements developed on a prototype vibrating screen now undergoing site testing at an iron ore mine in Western Australia, according to the company.
“The five larger screens feature laminated side plates to maintain structural integrity and reduce stress concentrations associated with the projected process tonnages,” Schenck explained. “Additionally, machined transition flanges are welded in a 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 and feature a more robust design. They are also equipped with exchangeable liners and an upgraded transition hopper to improve operational availability and performance, the company said.
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, Schenck added.
Project manager, Lauren Williams, said: “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.
“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. We are delivering an integrated package of screens and feeders to optimise availability and productivity and represent the best value for money.”
