Gyratory crushers are principally used in surface-crushing plants. The gyratory crusher (Figure 6.5) consists essentially of a long spindle, carrying a hard steel conical grinding element, the head, seated in an eccentric sleeve.The spindle is suspended from a "spider" and, as it rotates, normally between 85 and 150 rpm, it sweeps out a conical path within …
Roll Crushers. A. Gupta, D.S. Yan, in Mineral Processing Design and Operation, 2006 6.1.3 Roll Crusher Circuit Design. Roll crushers are generally not used as primary crushers for hard ores.

Another advantage of using an impact crusher is that it has a relatively low operating cost. The machine uses less energy than other crushers, such as jaw or cone crushers, and its impact force is more efficient at breaking down the material, resulting in less energy waste. However, there are some limitations to the use of impact crushers.
