    Application Of Analytical Hierarchy Process To Selection

    for this reason, gyratory, double toggle jaw, single toggle jaw, high speed roll crusher, low speed sizer, impactor, hammer mill and feeder breaker crushers were considered as alternatives and capacity, feed size, product size, rock compressive strength, abrasion index and mobility of crusher were considered as criteria.,review paper on swing jaw plate in jaw crusher machine,abstract – 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. 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.
