Abstract

An embodiment of the present invention provides a crushing cavity wear monitoring method, which belongs to the technical field of crushing equipment operation status monitoring. The crushing cavity wear monitoring method includes: obtaining feedback signals having cavity shape characteristics of the crushing cavity at each detection node at different positions of the crushing cavity, and proceeding to the next step when the feedback signals meet the first preset monitoring condition; Select the current detection node, and determine the crushing cavity’s size based on the distance between the current detection node and the adjacent detection node, the feedback signal corresponding to the current detection node, and the feedback signal corresponding to the adjacent detection node. Local characteristics of the cavity shape; when the wear rate corresponding to the local characteristics of the cavity shape satisfies the second preset monitoring condition, jump to the second step to form a cyclic monitoring process. The invention monitors the wear condition of the lining plate and the change of the structural shape of the crushing cavity by detecting the characteristics at the position and the current detection local area characteristics, can predict the working life of the lining plate and create conditions for reasonably formulating the operation and maintenance plan of the crusher.

Description

technical field [0001] The invention relates to the technical field of crushing equipment operation status monitoring, in particular to a crushing cavity wear monitoring method and a monitoring structure thereof. Background technique [0002] The working mechanism of the crusher is composed of a fixed liner and a movable liner, and the area between the working surfaces is the crushing chamber. During the crushing process, the movable liner swings according to a certain rule relative to the fixed liner to crush the material in the crushing cavity, making the particle size of the material continuously smaller until it is discharged out of the crushing cavity. [0003] During the crushing process, the materials in the crushing cavity will wear the fixed liner and the movable liner, and this wear will change the shape of the crushing cavity, resulting in the deterioration of the crushed product quality. There are two main methods for evaluating the amount of liner wear and its ...
