Secondary Crushing Equipment - 911 Metallurgist

28/02/2016  The term “secondary crushing” has become well established and familiar through long usage; it applies to the crushing stage, either single or multiple, which follows immediately after the primary crusher, taking all or a portion of the product of the primary crushing stage as its feed.The term should not be used, as it sometimes is, to designate a particular type or size of crusher because ...

Secondary Tertiary Crushing Circuits - 911 Metallurgist

24/07/2015  The coarse material will be crushed by the secondary crusher. The fines will be taken out of the circuit. Once the secondary has finished with the ore it will be reclassified by a second set of screens with the oversize going to the tertiary crusher. The discharge of the tertiary is reintroduced to the screen deck to ensure that the ore size is uniform.

02/09/2019  Most secondary crushers are cone crushers or horizontal-shaft impact crushers. Tertiary and quaternary crushers are usually cone crushers, although some applications can call for vertical-shaft impact crushers in these stages. GYRATORY CRUSHER. A gyratory crusher uses a mantle that gyrates, or rotates, within a concave bowl. As the mantle makes contact with the bowl during gyration, it creates compressive force, which fractures the rock. The gyratory crusher

Maximising productivity from secondary cone crushers

23/05/2016  A secondary cone crusher achieves its best work when fines smaller than the desired crusher product are removed from the feed. When a crusher is operating with a full chamber, the nominal top size of the crusher discharge is approximately 1.6 times the Closed Side Setting (CSS) of a top performing secondary cone crusher.

Primary Crushing - 911 Metallurgist

26/02/2016  Which Crusher is the Best Primary Rock Breaker. Since the minimum dimension of the feed opening of a crusher determines the maximum size of lump that it can take, the choice of a primary breaker is dependent as much on the size of the feed as on the hourly tonnage. Thus a 15 in. by 24 in. jaw crusher would be suitable for a small mine hoisting 300 tons in eight hours from underground
