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.”
