Question: In iron ore mining, sizing is used to crush and separate the mined ore into different size fractions that are used indifferent processing units. Mined iron ore in the size range 100-200mm is fed to a jaw crusher that crushes the feedto less than 40 mm . This crushed material is then fed to a series of vibrating screens.

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.
