(PDF) DYNAMIC ANALYSIS FOR BALL MILL …
The dynamic analysis of ball mill foundation is a typical problem of soil-structure interaction, and the sub-structure method is used to estimate the structural vibration.
BALL MILL GEARBOX PROBLEM - Vibration
From “The Gear Analysis Handbook” by Mr. James Taylor we also read the following table relating gear common factors to gear life: COMMON FACTOR % OF LIFE EXPECTED 1 100 2 50 3 33 4 25 5 20 6 16 7 14 This table follows the formula as follows: % Gear Life Expected = 100/GCF. VIBRATION DATA: •Vibration data was first collected from both 1A & 1B Ball Mill Drives under normal load (route ...

Vibration Feature Extraction and Analysis of …
The vibration signal analysis for lab model sag mill is same as that of ball mill, but the frequency of operation of vibration signal and impact strengths are different [8]. Sag mill will require a higher value of g and BW of the sensor due to higher stiffness compared to that of ball mill (as the length of the mills is accounted). The kinetics of the industrial wet mill varies due to its ...

An Experimental Investigation into Torsional Vibration in ...
This stone describes an experimental investigation of the torsional vibration of a ball mill with a particular emphasis on the damping of the mill itself. It was considered possible that the mill could be a significant source of energy dissipation for torsional vibration. A small batch ball mill was investigated using a servo motor as both the drive and a torsional exciter. The main parameters ...
