The width of the jaw determines capacity. Jaw crusher output gradation is controlled by the closed side setting. This is the adjustable opening at the bottom of the jaw. With a 24" top size limit and an 8:1 reduction ration, the closed side setting should be no smaller than 3". A well designed jaw should be 80 to 85 percent efficient.
While various crusher sizes have similar CSS range spans, some crushers operate in a bit tighter CSS range than others. The key is looking at the desired reduction ratio, or how far you wish to break material down in one pass. Industry standards commonly dictate that the ideal reduction ratio of a jaw crusher should be 6-to-1.
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.
