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.
