Cone crusher and processing plant for mineral material

摘要

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.

主权项

1. A cone crusher comprising:
a frame; an outer blade which is adapted to be locked to the frame; an inner blade which is eccentrically and vertically movable relative to the outer blade, wherein the inner blade and the outer blade define therebetween a crushing chamber; a main shaft which is stationary relative to the frame, the main shaft including a hollow space; an eccentric which is bearing-mounted on the main shaft; a support cone on which the inner blade is arranged; an adjustment shaft positioned in the hollow space of the main shaft and configured to support the support cone, wherein the adjustment shaft is vertically movable from below; a load cylinder arranged to surround a lower end of the main shaft, wherein the load cylinder comprises an adjustment piston positioned on a lower end of the adjustment shaft; a pressure medium supply arranged to supply a pressurized volume of the medium under the adjustment piston for moving vertically the adjustment shaft; and a lubricant supply arranged above the adjustment piston for directing lubricant through the hollow space between the main shaft and the adjustment shaft to targets to be lubricated, wherein the main shaft is fixed stationary to the frame such that the lower end of the main shaft extends outside the frame and under the frame and the lubricant supply is arranged from outside the frame to the extending part of the main shaft outside of the frame and through the main shaft to the hollow space.
