Investigation of Effect of Without Stiffener on Swing Jaw Crusher Plate by Finite Element Analysis

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 the maximum force exerted by the toggle for energy considerations. Thus a swing plate, stiff enough to crush taconite with an unconfined compressive strength (qu) of up to 308 MPa, may be overdesigned (and, most importantly, overweight) for crushing a softer fragmental limestone, amphibolites. Design of lighter weight jaw crushers will require a more precise accounting of the stresses and deflections in the crushing plates than is available with traditional techniques. Efforts to decrease energy consumed in crushing have lead to consideration of decreasing the weight of the swing plate of jaw crushers for easily crushed material. In the propose work the design of the swing jaw plate using point-load deformation failure relationships along with interactive failure of rock particles as a model for such a weight reduction. The design of the corrugated swing jaw plate will carry out by using CAD i.e. jaw crusher plate has been solid modelled by using Solid Works 2013. The calculated dimensions are validated with the drawing of reputed manufacturers. Finite Element Analysis of jaw plates are carried out by using ANSYS 14.5 software. The theoretical design calculations of jaw plates of the jaw crusher have been carried out.
