In-Pit Crushers; the Key to Hard-Rock Conveying The essential task of the in-pit crusher in a belt conveyor transport system is to reduce blasted material to a conveyable size. Crushers for this purpose are almost exclusively of the low crushing ratio type (up to 1 : 10), i.e. so- called primary or pre-crushers, designed as mobile or semi-mobile units.
