2021-4-21 Secondary Crushing. This follows after primary crushing and is done when further reduction is a necessity. The amount of reduction that takes place in this stage depends on how fine you want your finished product to appear. The Cone, although can serve as a primary crusher is commonly categorized as a secondary crusher. More Details

Primary Crusher an overview ScienceDirect Topics

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.

Primary Crushing SpringerLink

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”.
