The settings are based on the crushing characteristic of the material being fed and the desired final product size and size distribution.  There are no hard and fast rules.  But in general (very very generally, with many exceptions) crushers will do a 4 to 1 up to a 10 to 1 reduction (mostly dependent on the hardness and friability).

As with any mining related question, it depends and the only positive way to determine is to run tests.

The ore come from a Primary crusher and be scalped. The coarse material will be crushed by the secondary crusher. 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.
