<p>A cone crusher having a frame, an outer blade adapted to be locked to the frame, an inner blade eccentrically and vertically movable relative to the outer blade, and the inner blade and the outer blade define there between a crushing chamber, a main shaft which is stationary relative to the frame, an eccentric bearing-mounted on the main shaft, a support cone on which the inner blade is arranged, and an adjustment shaft by means of which the support cone is vertically movable from below. A hollow space is arranged inside the main shaft, the adjustment shaft is arranged to the hollow space, a load cylinder is arranged to a lower end of the main shaft which load cylinder comprises an adjustment piston acting to a lower end of the adjustment shaft, a pressure medium supply is arranged to a pressure volume under the adjustment piston for moving vertically the adjustment shaft, and a lubricant supply is arranged above the adjustment piston for directing lubricant via the hollow space to targets to be lubricated. The main shaft is fixed stationary to the frame such that the lower end of the main shaft extends outside the frame under the frame and that the lubricant supply is arranged from outside to the outside extending part of the main shaft and through the main shaft to the hollow space.</p> |
