Embodiment Construction

[0038] In the following description, the same reference numerals denote the same elements. It should be understood that the drawings shown are not exactly to scale and that the drawings are primarily for the purpose of illustrating some exemplary embodiments of the invention.

[0039] figure 1 A cone crusher is shown comprising a frame 1 and an upper part 2 of the crusher attached to the frame, to which the outer blades 3 of the crusher are attached. The outer blades can move vertically when the crushing chamber 4 is not loaded.

[0040] The crushing chamber 4 of the cone crusher is formed between the outer blade 3 and the inner blade 5 . During a crushing event, the position of the inner blade 5 changes relative to the outer blade 3, preferably as a combination of radial movement and movement around the axis of the inner blade. Optionally or additionally, the inner blade 5 can move vertically during the crushing process or in an unloaded state (the so-called idle state) si...

Abstract

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.

Description

technical field [0001] The present invention relates to a cone crusher comprising an outer blade and an inner blade movable within the outer blade, the cone crusher being suitable for crushing mineral material. The present invention relates particularly, but not exclusively, to a cone crusher having an inner blade movable in a vertical direction by an adjustment shaft positioned within the main shaft of the crusher. Further, the invention relates to a processing plant comprising a cone crusher. Background technique [0002] In rotary and cone crushers, the relative position of the inner and outer wear parts is brought closer together by adjusting the inner blade up or the unloaded outer blade down. [0003] In known solutions, a significant increase in the height of the crusher is disadvantageous when the adjustment distance is increased. An increase in the height of the entire crushing plant is disadvantageous when the height of the construction is increased, which in par...
