Understanding Types of Jaw Crusher: A Comprehensive …
— Now, when you look at secondary crushing, it's all about finessing materials that have already been roughed up by a primary crusher. This time, the pieces coming in are usually between 100 and 250 mm (4 to 10 inches), and the aim is to get them even smaller, down to about 25 to 80 mm (1 to 3 inches).
Secondary & Tertiary Crushing Circuits
This one involves both SECONDARY and TERTIARY crushing. This circuit is employed where either the tonnage or the work index of the ore is high enough to require that the crushing be done in stages. Again the ore will come from a Primary crusher and be scalped. The coarse material will be crushed by the secondary crusher.
Primary Crushing
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".
