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.

Iron Ore: From Mining to Processing to Dust Control
Mining iron ore typically involves finding a fertile site, drilling and blasting the ore, and then transporting it to the primary crusher for processing. Crushed ore is sorted over screens and resized to different specifications (lump and refined products). After the processing, a stacker builds a stockpile in the stockyards.

Primary crushing brings run-of-mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below “Dry” crushing includes work on ore as mined, which may be somewhat moist when delivered. It is succeeded by comminution in water, arbitrarily called “grinding”.

Crushing is accomplished by compression of the ore against rigid surfaces or by impact against surfaces in a rigidly constrained motion path. Crushing is the first mechanical stage in the process of comminution. Stages of crushing: Primary crushing → Run-of-mine ore (ROM) reduced to 10-20 cm (4"-8"), ( " = inch = 2.54 cm)
