Primary crushing in the mining industry refers to the initial stage of reducing large rocks or ore into smaller pieces. This is typically done using mechanical equipment such as jaw crushers or gyratory crushers.
All crusher types with 100+ years of experience. Our crushers are fit for aggregates production, construction material recycling and mining operations.
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".
