SUMMARY OF COMMON FAN VIBRATION PROBLEMS: (Detected Using Vibration Analysis) 1. Unbalance of Overhung Fan Rotating Parts (Fan Wheel or Drive Sheave): Overhung Rotor Unbalance will cause high 1X RPM in both the axial and radial directions. Axial readings tend to be in-phase and steady, whereas radial phase readings might be unsteady.

Results show that while vibration levels remained within safe limits, increased readings in specific areas, particularly at the Crusher NDE in axial direction under load conditions, suggest potential issues like misalignment or bearing wear. Prominent vibration peaks at lower frequencies in the spectrum further support these findings.

Why Vibration Analysis Matters for Fixed Jaw Crushers. Fixed jaw crushers are robust machines designed to crush hard materials like granite, basalte, et concrete into gravel or aggregates.Cependant, their heavy-duty operation generates significant mechanical stress, leading to wear on components like the fixed jaw plate, eccentric shaft, and bearings.
