Paper Details

stiffness of swing plates has not been varied with changes in rock strength. Rock strength has only been ofinterest because of the need to know the maximum force exerted by the toggle for energy considerations. Thus a swingplate, stiff enough to crush taconite with an unconfined compressive strength (q ) of up to 308 MPa, may be overdesigned(and, most importantly, overweight) for crushing a softer fragmental limestone, amphibolites. Design of lighter weightjaw crushers will require a more precise accounting of the stresses and deflections in the crushing plates than isavailable with traditional techniques.Efforts to decrease energy consumed in crushing have lead to consideration of decreasing the weight of the swing plateof jaw crushers for easily crushed material. In the present work the design of the swing jaw plate using point-loaddeformation failure (PDF) relationships along with interactive failure of rock particles as a model for such a weightreduction. The design of the corrugated swing jaw plate is carried out by using CAD i.e. jaw crusher plate has been solidmodeled by using CatiaV5R15. The calculated dimensions are validated with the drawing of reputed manufacturers.Finite Element Analysis of jaw plates are carried out by using ALGOR V19 software. Computerization of the theoreticaldesign calculations of jaw plates of the jaw crusher has been carried out. The computerized program facilitates for quickdesign of the plates of the jaw crusher.The different comparisons of corrugated swing jaw plates behavior, calculated with the traditional and the new FEAfailure models with stiffeners, shows that some 10-25% savings in plate weight may be possible.
