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".

Producing such a fine crush generally requires multiple crushing stations of up to 4 being but as a minimum of 2 being oversized. The gape determines the maximum size of material that can be accepted. Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape.
The picture above shows an example of how the crushing plant can be divided into primary, secondary, and tertiary stages. The aggregate produced in a primary crusher is classified using a screen into a 0-20 mm fraction and typically a 20-150 mm fraction. The 0-20 mm fraction contains soil etc. and is generally considered to be of poor quality.
