The document summarizes vibration data collected from two identical ball mills (1A and 1B) at a power plant. Vibration readings were higher for nearly every measurement point on ball mill 1A compared to 1B when both were under normal load. Specifically, waveform and high-frequency vibration levels were significantly higher at the coupling-end pillow …
