Jaw crushers are mainly used as primary crushers. Their main purpose is to reduce rocks to smaller sizes for the next crushing stages. Jaw crushers are a popular alternative to primary gyratory crushers, since they can process large amounts of hard material efficiently.
Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher's two jaws; one is fixed while the other reciprocates. There are also primary and secondary types of these crushers.
With a gyratory crusher, at any cross section there are in effect two sets of jaws opening and shutting like jaw crushers. In fact, the gyratory crusher can be regarded as an infinitely large number of jaw crushers each of infinitely small width, and, as consequence, the same terms gape, set, and throw, have identical meaning in the case of the gyratory crusher.
Primary crushers are solidly built to receive large lumps of rock directly from the mines and designed for large tonnage throughputs. Basically, gyratory crushers consist of a fixed solid conical shell or bowl (also called concaves) and a solid cone within the bowl called a breaking head (Figure 5.1).The breaking head is fixed to a central spindle, which is hydraulically suspended or ...
