Selecting the right crusher | Pit & Quarry
A pit-portable primary crusher can be an economically sound solution in cases where the producer is crushing at the quarry face. In modern plants, it is often advantageous to use a moveable primary crusher so it can follow the movement of the face where raw material is extracted. Intermediate (secondary) crushing.

Haulage systems for open pit mines
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 ...

In Pit Crushing and Conveying Systems
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 ...
