Remote Monitoring for Critical Ball Mill Drive

This technical report outlines the implementation of remote monitoring at a cement production site to prevent unplanned failures in a critical ball mill drive system. The report details the proactive approach taken by AVT Reliability Ltd, utilizing their Machine Sentry® technology for continuous condition-based maintenance. It describes how the Remote Diagnostic Centre identified a rising trend in acceleration levels on the motor drive-end bearing, leading to increased monitoring frequency. Spectral analysis indicated bearing deterioration, prompting an Action Note for replacement to avoid in-service failure. The report documents the successful installation of a replacement motor and subsequent monitoring, which confirmed a return to satisfactory operational conditions. The findings emphasize the importance of early fault detection and planned interventions in maintaining production efficiency and minimizing downtime risks. The report also notes that current readings remain within acceptable thresholds, indicating effective management of the asset's condition.
