The hydraulic adjustment system performs three important functions: It raises or lowers the mantle as required to adjust the crusher setting. It absorbs shock loads with the hydraulic accumulator as the crushing load increases and decreases. It increases the open-side setting (OSS) when an uncrushable object passes through the crusher.

The majority of gyratory crushers are used as primaries, i.e. they receive the initial feed from the mine or quarry. The same type of crusher with chamber modifications is used as a secondary crusher, particularly when following a large primary crusher. The fine-reduction gyratory crusher can also be used for tertiary crushing.

As the feed moves towards the drive end of the cone crusher, its size decreases (due to the crushing action), and ever smaller pieces move towards the drive end of the crusher. After passing through the crusher, the product -now at a much-reduced size- is discharged through an opening in the bottom shell. Gyratory Crusher Operation
