This phenomena leads to higher capacity of the single toggle jaw crushers but it also results in higher wear of the crushing jaws. These type of jaw crushers are preferred for the crushing of softer particles. A comparison between two can also be seen in Figure 2.2 It shows the difference in the movement and the method of operation.

The single toggle jaw crusher has fewer bearings and shafts as compared to a double toggle jaw crusher. It has more planes of movement of the swinging jaw (Hinge door movement plus vertical up and down movement) which leads to higher throughput. On the downside, it produces more fines, and has a higher jaw plate consumption. Uses one …
