### PROBLEM

 ![](https://static.martin-eng.com/www.martin-eng.com/case-studies/P1156-1.jpg)Located in remote, high-altitude Indonesia, Freeport Indonesia (PTFI) is a high volume operation producing gold and copper. To handle the vast quantities of ore, the mine uses large, fast, high capacity conveyors. Belts are typically 1800 to 2100 mm (72 or 84 inches) in width, and operate at 4 m/sec (~800 fpm). To simplify supplier arrangements, PTFI sought one belt cleaner supplier who could provide both [installation](https://www.martin-eng.com/content/page/543/installation) and [service](https://www.martin-eng.com/content/page/544/conveyor-system-specialized-ongoing-maintenance). 

### SOLUTION

 ![](https://static.martin-eng.com/www.martin-eng.com/case-studies/P1156-2.jpg)Martin Engineering specialists from the USA and Brazil spent a week at the Grasberg site, working with personnel from Indonesia partner/distributor P.T. Suprabakti Mandiri (Supra) to prepare a detailed site survey. Their report reviewed every belt cleaner in the operation, and discussed the benefits of outsourcing the cleaner maintenance. The Martin Engineering/Supra partnership was awarded a contract for cleaner supply and maintenance. Supra has standardized its conveyor operations and implemented several improvements. Supra has a team of service technicians permanently based at the mill site. PTFI now leaves all belt cleaner service to the Martin Engineering/Supra crew. This crew is charged with all belt cleaner services, including planning, adjustments, and blade change-outs. 

### RESULTS

With the systemization of cleaners and the outsourcing of cleaner maintenance, PTFI has noted reduced levels of carryback. This provides the benefits of improved component life and reduced cleanup labor. Working together, Martin Engineering, Supra, and PTFI anticipate continued improvement in the performance and life of belt cleaners and other conveyor components. The result is reduced fugitive material and improved conveying for the Grasberg operation.
