Problems solved by technology

This method of centering and sealing the case is time consuming considering that the positioning of the wedges is done by hand
This also poses a safety risk as the casings (mostly having a weight of 5 to 13 tons) are supported by hydraulic or other support means when manual positioning of the wedges is performed

Abstract

The invention relates to a sealing element (10) for a gyratory crusher (110) having a main shaft (20) and a casing (30). The sealing member (10) comprises a first side (11) and an opposite second side (12), the first side (11) being arrangeable on the circumference of the inner wall (24) of the casing (20) of the gyratory crusher (110) At least a part of the second side (12) is at a distance from the first side (11), the distance is not less than the difference between the radius of the inner wall of the casing and the radius of the outer wall of the main shaft, and the sealing member can be arranged in the casing At the inner wall of the main shaft, the sealing member contacts the main shaft at the outer wall of the main shaft to seal the space between the housing and the main shaft. The sealing member (10) provides an efficient and safe way of mounting the casing of the gyratory crusher.

Description

technical field [0001] The present invention relates to the field of gyratory crushers, and more particularly to a sealing member for use between the casing of a gyratory crusher and the taper of the main shaft of such a gyratory crusher, And a gyratory crusher including such a sealing member. Background technique [0002] Gyratory crushers generally include a concave surface and a conical head. The inner cone has a slight circular motion produced by the eccentric arrangement. The material to be broken travels down between the two surfaces, being gradually broken until it is small enough to fall through the gap between the two surfaces. Gyratory crushers are usually classified by size, either by the gap between the two surfaces and the diameter of the case, or by the size of the receiving opening. The crushing action is caused by the closing of the gap between a movable casing mounted on the main shaft and a fixed concave liner mounted on the main frame of the crusher. T...
