In-pit crushing and conveying (IPCC) systems are currently receiving more attention as a result of the existing characteristics of open-pit mining operatio …
IPCC systems consist of the application of a fully mobile, semi-mobile or fixed-in-pit primary crusher, which is coupled to a conveyor system. IPCC systems could lead to the partial or complete substitute for trucks because of their lower operating, maintenance and energy costs for conveyors. There are five possible conveying systems: In-pit ...
