Cone Crusher Explained
Cone Crushers; Typically, the initial crushing stage is completed using either gyratory crushers or jaw crushers. It is often the case that there will be only one crusher installed, and this will be referred to as the primary crusher. Cone crushers are more often used for 2nd, 3rd & 4th stage crushing steps (although not always).

Secondary & Tertiary Crushing Circuits
Again the ore will come from a Primary crusher and be scalped. 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.

TERTIARY CRUSHERS
After primary and secondary crushing and comminution, it can also be defined as the process of lower grams to be used in construction processes. Tertiary crushers are used not only in crushing and comminution processes, but also in screening processes. The screening mechanism is very fast and bi-directional.

5.1.1 Cone crushers Cone crushers are commonly used for secondary, tertiary and quaternary crushing duties. Two variations are available
Gyratory crushers are similar to cone crushers; they are frequently used in large-throughput primary crushing roles. Typically, they have larger capacities (up to 8000 tph) compared to jaw crushers (up to 1500 tph). Gyratory operate at a slower speed than cone crushers, typically in the range 85 to 105 rpm. They do not require feed mechanisms

Cone crushers were originally designed and developed by Symons around 1920 and therefore are often described as Symons cone crushers. As the mechanisms of crushing in these crushers are similar to gyratory crushers their designs are similar, but in this case the spindle is supported at the bottom of the gyrating cone instead of being suspended as in larger gyratory crushers.

Jaw Crusher vs Cone Crusher: A Comparison
Cone crushers take care of secondary and tertiary crushing applications. Fine and medium-sized aggregates (used in asphalt and concrete, for example) are created by an eccentrically rotating shaft that grinds the rocks between a robust metal cone and a fixed wall. The Blackhawk 100 Cone Crusher is an example of a powerful cone crushing machine.
