Whenever you need a jaw crusher that takes the brunt of the initial reduction in size, impact crushers would not be an option. Also if material quality is not an issue, you might want to consider a jaw and cone crusher over an impact ...
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.
