The HRC-3000 will perform tertiary crushing in the comminution circuit, which includes crushers and ball mills (also supplied by Metso) and will provide a highly efficient solution for this application.
“Operating costs are increasing throughout the industry, with power being a key component, and our customers are looking for more efficient technology to achieve the best returns in these circumstances,” says Andy Lingenfelter, Metso's global key account manager for
Metso says that the HRC's ability to meet the demands of this application is a result of its innovative design, which improves throughput and efficiency of the existing HPGR technology. Over 8,000 hours of testing, including 4,000 hours in a pilot plant operating at Morenci, have proven the design and efficiency of the HRC.
Design features include a patented arch frame to eliminate downtime and flanges to maintain wear and increase throughput, and these changes were implemented for the type of application in which the HRC-3000, scheduled to be online by early 2014, will be operating: high-tonnage tertiary crushing of hard rock.
“One of the reasons our customers are looking at HRC technology is because they see how our design can provide long-term benefits in operating costs,” says Lingenfelter.
