The 24-7 operation of the pelletizer furnace necessitates the constant operation of the cooling fans. The operating environment of the fans cause a buildup on the fan blades. Normal build up is consistent and the fan runs in a balanced condition. When the buildup gets thicker, chunks can break free and cause an unbalanced condition. Left to run in this condition, the fan can fail. The in-house vibration analyst performs monthly routes, but the sporadic nature of the out-of-balance condition necessitates a constant monitoring system be installed.
The AssetScan vibration monitoring system is installed at the fan bearings and monitors around the clock, alerting when an exception occurs.
