3/1/2019· Efficiency can be defined by the ratio of work done by a machine to the energy supplied to it. To apply what this means jaws generally produce the coarsest material because they break the rock by the natural inherent lines of weakness. A jaw crusher can be an excellent primary crusher when used to prepare rock for subsequent processing stages such as washing, classifying or a secondary

CERAMIC MATERIALS I

The gyratory, jaw, cone, and roll crushers crush rock by applying high compressive forces to each rock. Another type of crusher accomplishes similar results using impact hammers or blow bars mounted on a rotor, thereby producing high kinetic energy impacts on each rock at velocities of around 30 m/s. These impact crushers are capable of producing a high ratio of size reduction in one stage of crushing. However, due to the high
