Abrasion monitoring method and structure for crushing cavity

Abstract

The embodimentof the invention provides an abrasion monitoring method for a crushing cavity, and belongs to the technical field of monitoring of the operating state of crushing equipment. The abrasionmonitoring method for the crushing cavity comprises the steps that feedback signals having cavity characteristics of the crushing cavity and acquired on all detection nodes located at different positions of the crushing cavity are acquired, and the next step is conducted when the feedback signal meets a first preset monitoring condition; the current detection node is selected, local cavity characteristics of the crushing cavity are determined according to intra-node characteristics between the current detection node and the adjacent detection node, the feedback signal of the current detectionnode and the feedback signal of the adjacent detection node; and when the local cavity characteristics meet a second preset monitoring condition, the second step is conducted again, so that a cyclicmonitoring process is formed. According to the abrasion monitoring method for the crushing cavity, the abrasion condition of a lining plate and the structural shape changes of the crushing cavity aremonitored according to the characteristics at detection points and the local characteristics of the current detection position, the working life of the lining plate can be predicted, and conditions are created for reasonable planning of operation and maintenance of a crushing machine.

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 ...

Problems solved by technology

[0016] The purpose of the embodiments of the present invention is to provide a crushing chamber wear monitoring method and its monitoring structure, which aims to solve the problem that the existing technology cannot update and predict the life of the liner according to the dynamic use of the crusher, and cannot predict the wear of the liner that is about to reach the wear limit in advance. Replacement or maintenance of the board, unable to monitor and detect the characteristics of local areas between nodes, and the crusher has technical problems such as high operating costs and high wear rates
