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".
