Abstract

A cone crusher has an outer crushing shell and an inner crushing shell with a crushing gap formed therebetween. The outer crushing shell is supported on an upper frame member in threaded engagement with a lower frame member. The threaded engagement is configured for adjusting the vertical position of the outer crushing shell relative to the lower frame member so as to permit adjustment of the width of the crushing gap. The upper frame member is provided with a circumferential gear ring for turning the upper frame member in the threaded engagement. The gear ring is connected to the upper frame member in a rotationally locked and vertically slidable manner. The cone crusher includes a clamping arrangement for vertically clamping the gear ring between an upper clamping member and a lower clamping member.
