摘要

To be fair, crushers do not often hit the headlines. Hidden away in some dark cavern, or masked by ranks of tires and gabions along a pit bench, it is hard for a crusher to compete with the higher visibility of a new truck fleet or drill rig. Yet an effective crusher is a key component of any mineral-production system, paving the way for all of the subsequent stages of extraction technology. The crusher goes down, and the mine marks time. One of the fundamental processes in mineral recovery, rock breaking absorbs progressively greater energy inputs as size reduction proceeds. Even primary crushing is energy-intensive, with the optimum relationship between blasting fragmentation, crushing capacity and concentrator throughput liable to change over time with altering orebody characteristics.
