Gyratory and Cone Crusher - ScienceDirect

 · Figure 5.1 is a typical sketch of a large gyratory crusher used as a primary crusher to reduce the size of large pieces of rocks produced during blasting in mines. Variations in the design of the breaking head and the mantle have been adopted by different manufacturers. Such variations are adopted from studies on stress distributions of component parts endured during the crushing operation.
