Assessing the energy efficiency of a jaw crusher
A jaw crusher (see Fig. 2) is a comminution device 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 convex. The moving plate applies the force of impact on the particles held against the stationary plate.
