JAW CRUSHER. 8:1 maximum reduction ratio for compression crushing, this is normally used as a primary crusher. Jaws perform well in many materials. Yields low wear cost per ton in hard abrasive deposits, minimal fines but produces little finished (under 1") product which places more load on the crushers downstream in the circuit.

Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.

The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. It …

The crushing ratio of a jaw crusher results from the maximum achievable final fineness in relation to the maximum feed size. For Retsch jaw crushers, this lies between 26 and 220. A high value reflects the capacity of a jaw crusher to accept large sample pieces and provide powerful crushing performance, resulting in high final fineness.
