Crusher - an overview | ScienceDirect Topics

Crushed ore feeds this bin continuously and the bin overflows to a small conveyor feeding a dead stockpile. In the event of a primary crusher failure, the crusher loader is used to reclaim the stockpile via the surge bin, which doubles as an emergency hopper. • For coarse ore, the next alternative is a coarse ore stockpile.
