Hence, circuit capacities of one to a few hundred tonnes per hour were common practice. Because of high ore grade, these operations could produce enough metal to underpin profitable operation. As shown in Fig. 2a, a large jaw crusher was used to reduce ore from the mine to an 80% passing size (P80) of 100–150 mm.

The jaw crusher will handle sticky,'or dirty feed better than the gyratory, there being no diaphragm below the crushing chamber on which such material can pack. Routine maintenance and repair jobs are generally more easily accomplished on the jaw crusher than on the gyratory. Major repairs are about a stand-off.
