CONE CRUSHER AND PROCESSING PLANT FOR MINERAL MATERIAL

摘要

A cone crusher comprising a frame (1), an outer blade (3) which is adapted to be locked to the frame, an inner blade (5) which is eccentrically and vertically movable relative to the outer blade, and the inner blade and the outer blade define there between a crushing chamber (4), a main shaft (7) which is stationary relative to the frame, an eccentric (9) which is bearing-mounted on the main shaft, a support cone (11) on which the inner blade is arranged, and an adjustment shaft (14) by means of which the support cone is vertically movable from below. A hollow space (13) is arranged inside the main shaft (7), the adjustment shaft (14) is arranged to the hollow space, a load cylinder (30) is arranged to a lower end (7') of the main shaft which load cylinder comprises an adjustment piston (33) acting to a lower end (27) of the adjustment shaft, a pressure medium supply is arranged to a pressure volume (39) under the adjustment piston for moving vertically the adjustment shaft, and a lubricant supply is arranged above the adjustment piston (33) for directing lubricant via the hollow space (13) to targets to be lubricated. A processing plant (400) comprising a cone crusher.
