BALL MILL GEARBOX PROBLEM - Vibration

•Additional vibration data was collected from the motor gearbox of the 1A Ball Mill Drive under no load. •To determine what problems (if any) existed with the drive, a comparison of the route vibration data between 1A 1B Ball Mills was made as well as between loaded unloaded data at 1A Ball Mill.

High vibration on the ball mill drive train A and B AMP ...

High vibration on the ball mill drive train A and B. We are experiencing high vibration on our dual drive ball mill. The high vibration is on the motor DE bearing on axial direction. Dominant frequency is girth and pinion gear mesh. See attached spectrums and trends.

High vibrations on a ball mill AMP Maintenance Forums

21-01-2011  Now, when the mill is started, vibration values are around 14 mm/s, first 4 harmonics of the GM, and then for about half an hour they go up to 28 mm/s (again 4 harmonics of GM) - in horizontal direction while in the vertical and axial direction there is no such change.

High Vibration Ball Mill Duel Pinion Drive - Mechanical ...

A vibration survey was carried on this Ball Mill with a duel pinion drive. The vibration is high in all planes on both sides of the Mill or both pinion drives. The measurements were similar in velocity on the motor , gearbox and both pinion bearings. The recommendations for repairs was close to exactly the same for both drives.

HD Technologies Case Study: Ball Mill Bearing Damage -

11-09-2019  The HD ENV Filter 3 trend on the DE bearing follows a pattern similar to the SPM HD trend on the NDE bearing, and also has a spectrum showing BPFO match. Due to the close distance between the two bearings, the vibration sensor mounted on the DE bearing picks up the signal from the NDE bearing. The vibration readings do not show any sign of damage.

High vibration on the ball mill drive train A and B AMP ...

We are experiencing high vibration on our dual drive ball mill. The high vibration is on the motor DE bearing on axial direction. Dominant frequency is girth and pinion gear mesh. See attached spectrums and trends. Gearbox hold-down bolts are breaking due to high vibration.

Causes and solutions of severe vibration of ball mill ...

In the daily production of the ball mill, there will always be some sudden failures, such as severe vibration of the ball mill gear, cracking of the large gear ring of the ball mill, or the sudden increase in the temperature of the ball mill bearing. accident.Fodamon engineers shares the reasons and solutions of the severe vibration of the ball mill pinion.

AN EXPERIMENTAL ANALYSIS OF VIBRATION OF A BALL MILL

ball mill. After that the measurement of accelerations of vibration at housings of bearings has been performed. Due to the production requirements the capacity of the ball mill is variable and therefore the torque on the ball mill drive is also variable. Measurement has been done for two different capacities.

High Vibration Ball Mill Duel Pinion Drive - Mechanical ...

A vibration survey was carried on this Ball Mill with a duel pinion drive. The vibration is high in all planes on both sides of the Mill or both pinion drives. The measurements were similar in velocity on the motor , gearbox and both pinion bearings.

Vibration monitoring to boost efficiency

using vibration monitoring are the motor and gearbox assemblies. For a typical crusher motor, accelerometers are mounted radially on the Drive End (DE) and Non-Drive End (NDE), in order to monitor the motor bearing condition (g). ‘Accelerometers used to measure vibration levels are usually easy to install and use.’

Condition Monitoring of Ball Bearing Using Vibration ...

Ball Bearing, condition monitoring, vibration analysis, FFT analyzer, feature extraction. I. INTRODUCTION A ball bearing is a type of rolling element bearing that uses balls to maintain separation between moving parts of bearing. The purpose of ball bearing is to reduce the friction and support loads [1].

An Overview of Bearing Vibration Analysis

In this article the sources of bearing vibration are discussed along with the characteristic vibration frequencies that are likely to be generated. 2. Sources of Vibration Rolling contact bearings represent a complex vibration system whose components i.e. rolling elements, inner raceway, outer raceway and cage interact to generate complex vibration

Vibration Based Condition Monitoring ofRolling Mill

bearing reaction is then responsible for increase in vibration amplitude at respective frequency of a component. It means as bearing reaction increases conversely the amplitude will also increase. 4. ROLLING MILL: A rolling mill 2 of this company uses an 800 HP motor, which is used to transmit the power to the rolling mill.

(PDF) DYNAMIC ANALYSIS FOR BALL MILL FOUNDATION

For small ball mill, mill diameter less than 3.6 m, with small dynamic loads, the method of free vibration analysis can be used. This is also call modal analysis.

HD Technologies Case Study: Ball Mill Bearing Damage

The subject of this case study is the NDE (non-drive end) Pinion Bearing of Ball Mill No 8 in the Mill Dpt. in the flotation plant. The bearings on the pinion are of type 22380YMB. SPM HD Spectrum from the NDE bearing shows a clear match of the BPFO (Ball Pass Frequency Outer Race) symptom.

ABB knows the most common bearing diffi culties and how to ...

now summarise the most common bearing problems. Vibration Roller bearings are easily damaged from vibration when the motor is not running, so the rotor is locked during transportation. Ball bearings can sustain more vibration than roller bearings when not running. Both types can only withstand single and infrequent shocks of 2-3g

Vibration analysis of parallel misaligned shaft with ball ...

vibration levels (Ganeriwala et al., 1999; Piotrowski, 2006). Vibration due to misalignment is usually characterized by a 2X running speed component and high axial vibration levels. When a misaligned shaft is supported by rolling-element bearing, these characteristic frequencies may also appear. In this study a newly designed pin type of flexible

Motor Bearings, Not Just a Piece of Metal

3.1 Vibration Roller bearings are damaged easily from vibration when the motor is not running. Therefore the rotor is locked during transportation. Ball bearings can sustain more vibration than Roller bearings when not running. Both Roller and Ball bearings can only sustain single and infrequent shocks of 2 to 3 g without damage,

The Role of Vibration Monitoring in Predictive Maintenance

Bearing manufacturers give detailed guidelines as to what maintenance is required and when which is often overlooked. This can have disastrous consequences in terms of poor quality output, reduced plant efficiency or equipment failure. Monitoring the condition of rolling bearings is therefore essential and vibration based monitoring is more ...
