H-E PARTS INTERNATIONAL CRUSHING SOLUTIONS (HEPICS) SPECIALISES IN PROVIDING WEAR MANAGEMENT SOLUTIONS. HEPICS LINER DEVELOPMENT PROGRAM HAS BEEN DEVELOPED TO OPTIMISE LINER DESIGNS ON A SITE BY SITE BASIS AND INVOLVES THE ONGOING ANALYSIS OF OPERATIONAL REQUIREMENTS, MACHINE OPERATING PARAMETERS AND WORN LINER PROFILES.

Newmont Boddington (Boddington) is a mine-site located in Western Australia, producing gold and copper concentrate. Boddington contacted the HEPICS team when their OEM supplied liners for their Metso MP1000 secondary crushers weren’t lasting as long as expected. The initial expectation of the liners was that they would withstand 630,000 – 640,000 tonnes, but the OEM installed liners were only working to a life of 430,000 tonnes. To assist Boddington with improving their liners, HEPICS engineers performed an on-site evaluation of the existing liners using innovative 3D laser scanning technology. Customising a liner based on each sites unique application allows HEPICS to design and supply a liner that will perform well in the specific conditions and prolong the life of the liners on-site.

The objective of the Boddington liner development program was to reduce liner wear rates and extend time between liner change-outs. An added complication Boddington faced was extending specific liner sets to coincide with the majority of the liner change-outs, reducing the unnecessary costs associated with unexpected shutdowns.
