Jaw Crusher Reduction Ratio. Either an 8-to-1 or 6-to-1 ratio should be the target reduction ratio for maximum jaw crusher efficiency. This setting typically provides an ideal P80 factor—when 80% of crushed material produced by primary crushing will pass screening after processing. A smaller closed-side setting will produce more fines.
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.

Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1. The primary operating variable available on a crusher is the set and on jaw and gyratory the open-
The reduction ratio in crushing is the ratio of the feed size to the product size during a crushing operation. It usually varies, but the reduction ratio depends on the chamber and nut adjustments. However, the best particle shape is found in material about the same size as the CSS, which is …
between the jaw dies allowing the material to have more space to get out, while also enabling inter-particle crushing. This design principle results in an increase in both the capacity and the reduction ratio. Optimal nip angle ensures excellent bite in the cavity The correct nip angle between the movable and fixed jaw dies ensures good bite and
Calculating the Set Size when the Crusher Reduction Ratio and the Gape Size are Given. S = G / R r. Where: S = Set Size R r = Crusher Reduction Ratio G = Gape Size. Let's solve an example; Find the set size when the crusher reduction ratio is 10 and the gape size is 30.
