Abstract

A gyratory crusher of the type having a pair of crushing members such as a generally concial shaped head and a cooperating concave which surrounds the head to form an annular crushing chamber therewith. The concave and its supporting upper frame are spring loaded on the main frame and in a downward direction for cooperation with the crushing head. Means are provided for maintaining the compression in the springs which bias the upper frame and its concave downwardly on the main frame, this means being shiftable to an inoperative position while the crusher is operative and the means then being shiftable to a spring compression retaining position whereby the upper frame and its concave can be detached and removed from the main frame.
