Sealing member and mantle comprising such member, gyratory crusher and method of installing

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 wall of 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 a mantle of a gyratory crusher.
