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.

Normally ore is hauled by haul trucks from the blasted mine face to an ore pad in front of a crusher, where it is dumped into some form of pre-crusher stockpile. When required for crushing, the stockpiled ore is picked up by a front-end loader and dumped into the crusher. Following crushing the ore is stacked onto post-

Coarse crushing: the raw iron ore material in the silo is feeding evenly to the jaw crusher by the vibrating feeder for primary crushing. After primary crushing, the iron ore get together to transit stockpile by a small conveyor belt. Secondary crushing: the iron ore in transit stockpile transfer to the impact crusher for intermediate crushing.

The pebble accumulation can then be worked through during periods of increased SAG capacity (due to softer, finer ore, or other reasons). Obviously, the pebble stockpile must stay in balance. The last major decision for a pebble-crushing circuit is where to put the pebble-crusher product. Conventionally, crusher product was returned to SAG feed.

Crushing is typically a dry operation that is performed in two- or three-stages (i.e., primary, secondary, tertiary crushing). Lumps of run-of-mine ore as large as 1.5 m across are reduced in the primary crushing stage to 10–20 cm in heavy-duty machines. In most operations, the primary crushing schedule is the same as the mining schedule.

In most crushing installations a jaw crusher takes care of primary crushing. Plants with very high capacities that are common in mining and less popular in aggregates production, normally use a primary gyratory crusher. When the processed material is easy to crush and not very abrasive, an impact crusher may be the best choice for primary crushing.
