A new generation of high-efficiency coarse and medium-fine crushers: CI5X series impact crushers
·Traditionally in open pit mines the ore has been predominantly mined by conventional mining systems including shovels and trucks However with increasing operating costs associated with
·In pit crushing and conveying IPCC systems have attracted more interest among miners as an alternative to the conventional truck shovel transportation system
·Using an in pit crusher a combination of track mounted mobile crusher with mobile and fixed conveyor belts make it more competitive in compared to first method This combination is called In Pit
IPCC systems consist of a primary crusher installed in pit close to the active mining areas The crusher is used to crush mined material to a suitable size for transportation via a downstream conveyor system The conveyor then transports the crushed material out of the mine Material haulage is recognised as a significant contributor to both
Conventional truck haulage as today´s predominant means of material transport in open pit surface mines is well established with these systems providing excellent flexibility however they can also contribute up to 60% of the overall mining cost IPCC thus represents a viable safer more efficient and less fossil fuel dependent alternative
·Facility site selection such as Primary or in pit Crusher location is one of the most important steps in mine design process that has a significant impact on economy of the mining operation
In open pit mining two different options for extracting and hauling material have been established On the one hand shovel and truck only and on the other hand in pit crushing and conveying IPCC IPCC allows for reducing truck haulage in mines by moving the primary crusher closer to the shovel operating area for crushing and conveying
