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 present invention relates to a sealing member (10) for a gyratory crusher (110) having a main shaft (20) and a mantle (30). The sealing member (10) comprises a first side (11) and a second, opposing, side (12) and the first side (11) is arrangeable on a circumference of an inner wall (24) of the mantle (20) of the gyratory crusher (110) and at least a portion of the second side (12) is at a distance from the first side (11), the distance being not less than the difference between a radius of the inner wall of the mantle where the sealing member is arrangeable and a radius of the outer wallof the main shaft where the sealing is to contact the main shaft for sealing a space between the mantle and the main shaft. The sealing member (10) provides an efficient and safe way of installing amantle of a 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...
