PHM of Roller Tyre in Nonferrous Metal Crushing Process Based on DUAE

The roller mill is a crucial production equipment for the nonferrous metal heneficiation process, responsible for crushing ores. Over time, the roller tyre of the roller mill gradually wears down, ultimately impacting the crushing efficiency. Therefore, Prognostics and Health Management (PHM) of the roller tyre is crucial to enhancing the production efficiency of the roller mill. in this study, a PHM method based on Dual Autoencoder (DUAE) is proposed to predict the grinding roller tyre's service life. The effectiveness of the proposed PHM method is validated using actual data from a domestic concentrator. This research demonstrates that the PHM of roller tyres can be effectively conducted.
