The design of the swing jaw plate is proposed using point-load deformation failure relationships along with interactive failure of rock particles as a model for such a reduction in deflection value. Traditionally, stiffness of swing plates has not been varied with changes in rock strength. Rock strength has only been of interest because of the need to know …
