Coal mill degradation refers to the phenomenon where the performance of the coal mill gradually decreases during operation due to equipment aging,wear,and improper maintenance.The deterioration of coal mills can lead to a decrease in coal grinding efficiency and coal powder quality,which has a negative impact on boiler operation.Therefore,it is particularly important to promptly identify and address the issue of coal mill deterioration.This article provides an in-depth analysis of the wear mechanism of coal mill rollers,and based on the principle of wavelet analysis,constructs an analysis model for the degree of coal mill degradation,which can accurately reflect the trend of coal mill degradation,aiming to provide strong support for the maintenance and management of coal mills.
