  Detailed Reporting 
Fourways Crushing Plant/ Jaw Crusher - Motor 
Date: 21 January 2026 
Findings: Overall vibration on the motor NDE horizontal is trending upwards from 3.0 to 9.8 
mm/s RMS. Spectra shows a dominant 1x vibration, which is characteristic to structural 
looseness. Motor DE bearing exhibits a strong 1x vibration suspected from the crusher running 
speed, this characteristic to unbalance.   
Recommendations: Inspect and address any loose motor hold down bolts or weakened 
structures supporting the motor and the crusher. Inspect motor cooling fan and crusher pulleys 
for stuck dust accumulation and clean to remove dust accumulation.

Fourways Crushing Plant/ Cone Crusher A - Crusher 
Date: 21 January 2026 
Findings: Time waveform shows distinct impacting of up to 5.7 G’s, which can be associated 
with bearing fault. Suspected bearing defect at 225Hz. 
Recommendations: Ensure the crusher bearings are adequately lubricated. Continue to 
monitor and trend.

Fourways Crushing Plant/ Cone Crusher B - Motor 
Date: 21 January 2026 
Findings: Overall vibration on the motor DE Horizontal is trending upwards from 11.5 to 5.8 
mm/s RMS. Spectra shows 1x vibration which is characteristic to structural looseness. 
Recommendations: Inspect and address any loose motor hold down bolts or weakened 
structures supporting the motor. The recommended practice is to isolate the motor and crusher 
structural framework.

Date: 21 January 2026 
Findings: Overall vibration on the crusher NDE Horizontal is trending upwards from 9.2 to 16.4 
mm/s RMS. Time waveform plot shows distinct impacting of up to 14.8 G’s, which can be 
associated with bearing fault. Random broadband noise floors dominate the spectrum which is 
associated with lubrication fault. 
Recommendations: Ensure the crusher bearings are adequately lubricated. Continue to

Date: 21 January 2026 
Findings: Overall vibration on the motor DE vertical is trending upwards at 50.9 mm/s RMS. 
Spectra shows a strong 1x vibration which is characteristic to structural looseness. Axial 
vibration is upwards from 13.3 to 21.8 mm/s RMS, this is an indication of belt misalignment  
Recommendations: Address any loose motor hold down bolts, weakened structures to 
improve the structural rigidity. Inspect belts for wear and damage and replace as per condition, 
schedule for belt alignment. Visible cracked framework supporting the motor.

Observations 
1. Structures supporting the electrical motors on the screens, in particular screen 1 and 2, 
are damaged resulting in excessive vibrations. 
2. All the drives are running with inadequate belts and misaligned. 
3. Plan to reinforce the motor supporting structures to improve rigidity. 
4. Plan to isolate motor base-frames from the crusher to minimise transmitted vibrations.
