Jaw Crusher Comminution

Understanding comminution: Compression versus impact

Aug 18, 2020  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’s begun the reduction process earlier in the circuit.
