Problems solved by technology

[0004] One problem with this type of seal is that the seal ring is usually made of a polymer material (e.g. nylon)
Seal rings are relatively large and expensive components with high replacement costs
This sealing ring is also easily damaged by water and dust particles

Embodiment Construction

[0055] refer to figure 1 , The crusher includes: a frame 100 having an upper frame 101 and a lower frame 102 . The crushing head 103 is mounted on an elongated shaft 107 . A first (inner) crushing shell 105 is fixedly mounted on the crushing head 103 and a second (outer) crushing shell 106 is fixedly mounted at the upper frame 101 . A crushing zone 104 is formed between opposing crushing shells 105,106. A discharge zone 109 is positioned immediately below the crushing zone 104 and is partially defined by the lower stand 102 .

[0056] The upper frame 101 is further divided into: a top case 111 mounted on the lower frame 102 (alternatively referred to as a bottom case), and a support frame 114 extending from the top case 111 and representing The upper part of the crusher. Bracket 114 includes two diametrically opposed arms 110 extending radially outward from a central boss (not shown) positioned on a longitudinal axis 115 extending generally through the machine. Block 100 ...

Abstract

A gyratory crusher sealing assembly (124) to provide a seal between a discharge zone (109) positioned below a crushing chamber and a working part zone (128) of the crusher that accommodates various bearing assemblies and drive components that provide gyroscopic precession of the head (103) and inner crushing shell (105) within the crusher. The sealing assembly (124) includes: a reusable carrier ring (200) having a radially inner region (214), a radially outer region (216), an upper side (210) and a lower side (212); and at least one seal (202, 204a-c) releasably mounted on the carrier ring (200) that is arranged for sealing engagement with a sealing part (112, 120), wherein the seal (202, 204a-c) protrudes beyond a mounting region of the carrier ring (200) such that, in use, the seal (202,204a-c) maintains the carrier ring (200) out of engagement with the sealing part (112, 120).

Description

technical field [0001] The present invention relates to a seal assembly for a gyratory crusher and a gyratory crusher comprising said seal assembly. Background technique [0002] Gyratory crushers are used to crush ore, mineral and rock materials into smaller sizes. Typically, a crusher includes a crushing head mounted on an elongated main shaft. The first crushing shell (usually called the cover body) is installed on the crushing head, and the second crushing shell (usually called the concave body) is installed on the base, so that the first crushing shell and the second crushing shell together A crushing chamber is defined through which the material to be crushed passes. A drive device located in the lower region of the main shaft is configured to rotate an eccentric assembly arranged around the main shaft in order to cause the crushing head to perform a swiveling motion and crush material introduced into the crushing chamber. Examples of gyratory crushers are described...
