  • Jaw Crusher ScienceDirect

    01.01.2016· Jaw crushers are designed to impart an impact on a rock particle placed between a fixed and a moving plate (jaw). The faces of the plates are made of hardened steel. Both plates could be flat or the fixed plate flat and the moving plate convex. The surfaces of both plates could be plain or corrugated. The moving plate applies the force of impact on the particles held against the stationary

  • Analyzing the operation and design of a Jaw Crusher using

    The jaw crusher’s moving jaw undergoes two main types of motion, one resulting from the eccentric shaft movement, and the second from the toggle plate and the tension rod. Using simulation and the Discrete Element Method (DEM) it is possible to model the complex crushing process in order to optimize the operation and design of the machine.
