SHEDDING LIGHT ON SECONDARY CRUSHING B. Putland,
Secondary crushing of the SAG mill feed, when implemented correctly, has been shown to significantly reduce SAG mill and total circuit specific energy. Very fine feed, good process control and or the presence of some coarse rock in the feed (partial secondary crushing) has been required to make a successful project. The reason secondary

Secondary Crusher
In sand crushing plant The raw materials are first placed into elementary-crushing machine (jaw crusher) via vibrating feeder for crush, and so the elementary products are transferred through belt conveyor for your secondary-crushing machine (cone crusher) for secondary crushing. The vibrating screen separates the secondary products into two kinds.

Secondary & Tertiary Crushing Circuits
This one involves both SECONDARY and TERTIARY crushing. This circuit is employed where either the tonnage or the work index of the ore is high enough to require that the crushing be done in stages. Again the ore will come from a Primary crusher and be scalped. The coarse material will be crushed by the secondary crusher.

Secondary Crushing
Cone crushers are fed with prescreened material from the primary crusher (usually a jaw crusher or primary gyratory), and the secondary crusher should always, if possible, have a scalped feed. Ideally, the deck on the scalping screen should have a cut point equal to the closed side setting (CSS) of the crusher.

TECHNICAL NOTES 5 CRUSHERS
crushers of various size as a function of the open-side set. 5.1.1 Cone crushers Cone crushers are commonly used for secondary, tertiary and quaternary crushing duties. Two variations are available
Crushing is accomplished by compression of the ore against a rigid surface or by impact against a surface in a rigidly constrained motion path. Crushing is usually a dry process and carried out on ROM ore in succession of two or three stages, namely, by (1) primary, (2) secondary, and (3) tertiary crushers.
