6 Analysis of the vibration spectrum can be divided into 3 areas: Subsynchronous is less than 1x turning speed (TS) of the shaft and can identify problems with: belts, oil whirl/whip, rubs, loose roller bearing in housing, cage or train frequency of antifriction
Machine working condition affects the vibration levels. Therefore, one of the important monitoring methods of machine condition is vibration measurement and analysis. In this study, ball mill vibration analysis is done by the STD3300 data collector which is set at 21000 Hz frequency range. Two velocity sensors are used for vibration monitoring.
The dynamic analysis of ball mill foundation is a typical problem of soilstructure interaction, and the substructure method is used to estimate the structural vibration. In this study a. practical case of ball mill foundation is investigated to illustrate the approach and the dynamic. behaviour of structure.
A lowest efficiency of 93% corresponded to trunnion bearing temperature, pinion bearing temperature, mill motor temperature, mill motor vibration, pinion gear vibration of ⁰C, 44 ⁰C, 59 ⁰C, mm/s 2 and mm/s 2, respectively. Decrease in any of the influential factors considered improved ball mill efficiency accordingly.

The grinding process in the ball mill is due to the centrifugal force induced by the mill on the balls. This force depends on the weight of the balls and the ball mill rotational speed. At low speeds, the balls are at a fall state (Figure 9(a)). As the operating speed increases, the balls reach a higher helix angle before falling and repeating ...
