secondary crushers reduce the particle size of precrushed feed to 6 to 50 mm at much lower rates of throughput. Spring Swinging jaw Stationary jaw Hardened jaw faces Figure 5.1: Jaw crusher Gyratory crushers: A gyratory crusher may be looked upon as a jaw crusher with circular jaws, between which material is being crushed at some point at all ...

The primary gyratory crusher offers high capacity thanks to its generously dimensioned circular discharge opening (which provides a much larger area than that of the jaw crusher) and the continuous operation principle (while the reciprocating motion of the jaw crusher produces a batch crushing action).

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.

In summary, the operation of a jaw crusher is relatively simple. The material is fed into the crusher chamber from the top, and the jaws come together to create a V-shaped opening. The material is ...
