Schenck Process to deliver screens and feeders to copper mine

Schenck Process has been awarded a contract to design, manufacture, supply and commission vibrating screens and feeders for the greenfield Mina Justa copper mine in Peru.

The scope of the contract will include seven banana screens across three models, five diverging pan feeders and one grizzly feeder, with the process to be undertaken across a range of Schenck Process’ global business units.

The Mina Justa mine is being developed by Marcobre, a joint venture between Minsur, a mining company based in Peru, and Alxar, a subsidiary of Empresas Copec.

Schenck Process will complete all design at the company’s vibrating equipment design centre in Sydney, before manufacturing and testing takes place at its Chinese plant.

The company will deliver custom made screen panels from the company’s South African production facility. Commissioning is set to take place by the aftermarket services team in Chile.

Schenck Process’ screens include a number of mechanical and operational improvements developed on a prototype vibrating screen that is undergoing site testing at a Western Australian iron ore mine.

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 areas 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 with a more robust design, 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 six-dimension condition monitoring system, to track and alert operators to abnormal operating conditions.

“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,” project manager Lauren Williams said.

“We are delivering an integrated package of screens and feeders to optimise availability and productivity and represent the best value for money.”
