Embodiment Construction

[0029] See figure 1 The crusher includes a frame 100 having an upper frame 101 (usually called a top shell) and a lower frame 102 (usually called a bottom shell) centered on a longitudinal axis 109. The crushing head (not shown) is mounted on the elongated shaft (not shown). The first (inner) crushing shell (not shown) is fixedly installed on the crushing head, and the second (outer) crushing shell (not shown) is fixedly installed on the top shell 101. A crushing zone (not shown) is formed between the opposed crushing shells. The discharge zone (not shown) is located immediately below the crushing zone and is partially defined by the bottom shell 102.

[0030] The driving part (not shown) is coupled to the main shaft via the driving shaft 108 and a matching gear (not shown), so as to eccentrically rotate the main shaft about the longitudinal axis 109, and urge the head and the hood to perform a rotary swing movement, and The material introduced into the crushing cavity is crush...

Abstract

A crusher inspection hatch assembly (107) provided at a crusher. The hatch assembly comprises a frame (200) surrounding the hatch opening (301) and a door (201) to close the opening when the hatch is not in use. A plurality of attachment elements (406, 407) secure the door to the frame. Each attachment element comprises a shaft (407) and a nut (406) with at least the nut component of the attachment element being prevented from separation from the hatch assembly via at least one abutment flange (408, 409).

Description

Technical field [0001] The present invention relates to a crusher inspection hatch for a crusher, and specifically, but not exclusively, to a hatch assembly configured to prevent attachment of at least part of the element The attachment element is used to fix the hatch cover to the hatch opening provided at the crusher area. Background technique [0002] Rotary crushers are used to crush ores, minerals and rock materials into smaller sizes. Generally, the crusher includes a crushing head mounted on an elongated main shaft. The first crushing shell (usually referred to as the hood) is installed on the crushing head. And the second crushing shell (usually referred to as the recess) is installed on the frame, so that the first crushing shell and the second crushing shell together define a crushing gap through which materials to be crushed pass. The driving device positioned at the lower region of the main shaft is configured to rotate the eccentric component around the shaft to c...
