The condition monitoring and detection analysis of rotatory type of machines by means of vibration were studied [ 6 ]. Every part of the rotating machinery has some frequency, and for every frequency, there is amplitude. This amplitude changes whenever there is fault in the respective parts of the machinery.

Ball mills are extensively used in the size reduction process of different ores and minerals. The fill level inside a ball mill is a crucial parameter which needs to be monitored regularly for optimal operation of the ball mill. In this paper, a vibration monitoringbased method is proposed and tested for estimating the fill level inside a laboratoryscale ball mill. A vibration signal is ...

Case's description. A ball mill used in ore grinding had a history of anomalies in the concrete structural members, located below the support bearings of the drive pinion shaft. Excessive cracking and spalling were, at first, justified by the inadequate dynamic behavior of the set. In order to effectively diagnose and solve the occurrences ...

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 ...
