· A cone crusher in a secondary crushing appliion will typically work with a :1 to 5:1 reduction ratio. Tertiary cone crusher configurations typically work with a reduction ratio of :1 to 4:1. The reduction ratio is defined as the ratio of the feed size for which 80 per cent will pass (F80), divided by the product size for which 80 per cent will pass (P80). The reduction ratio for tough ...

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.
