Jaw crushers are generally considered a primary or first-stage crusher. The maximum feed size can be as large as 80–85% of the crusher's gape or depth, while reduction ratios range from 2–3 times. Cone crushers are typically used in the secondary or tertiary stage after a jaw crusher has begun the reduction process earlier in the circuit.

Types of Crushers: What You Need to Know
There are lots of different kinds of crushers from jaw crushers to impactors and cone crushers. Crushing is an versatile process and the kind of crusher you need depends on the 'stage' of crushing. The three main stages of crushing are primary, secondary, and tertiary - all of which have their own unique benefits.
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.
How Impact Crushers Work: A Comprehensive Guide
Crushing Equipment / March 11, 2023 / 5 minutes of reading. An impact crusher is a machine used to crush materials by impact energy. It works by feeding the material into a rotating rotor, which is equipped with a series of hammers. As the rotor spins, the hammers strike the material, causing it to break into smaller pieces.
Crusher surveys
The sampling of coarse particles, for example from the feed conveyor to the jaw crusher, will produce a large amount of sample. A recommended procedure requires 4-6 people, collects from 500 to 800 kg of rock, and takes up to 30 minutes to complete (that sample alone). I will have more details for you tomorrow.
