·It is suggested by Dean et al that truck haulage may still be required during each sinking phase of a mine though haul distance may be minimized by using the trucks to dump into the fully mobile crusher near the sinking activity [4] These systems are characterized by the loading unit dumping directly into the hopper of a fully mobile
·The types of primary crushers typically found in mining applications include Roll Crushers Sizers Feeder Breakers; Jaws Cones Impactors The right primary crusher for an application depends on several factors Material to be crushed Feed size Desired product size Capacity required Compressive strength of the feed Moisture content
·Depending on the design of the crusher machine a feeder may or may not be required before the primary crusher The haul trucks load the shot rock into the primary jaw crusher which feeds the rocks to a primary vibrating screen which directs larger stone to a surge pile and smaller stone to a stockpile The surge pile acts as a buffer between

·In pit crushing and conveying IPCC systems are currently receiving more attention as a result of the existing characteristics of open pit mining operations and what is likely to happen in the future The use of trucks and shovels for loading and hauling has been used as a dominant system in open pit and open cast mines due to their large scale operations
·{{image2 a r w 200}}One of the first steps in the process is to select the equipment to load the primary hopper The truck size and number of trucks or loaders needs to be determined to evaluate the hopper capacity Typically the minimum hopper live load capacity is about times the size of the unit dumping in the hopper
·hauling up the pit to a waste dump or to the primary crusher fixed or semi fixed conveyors move the material for the majority of the length Although there are a few varieties of IPCC systems; the main feature is that a smaller truck fleet is used where the primary material mover is the conveying system Shovels are used to load the
