Tumbling mills describe a class of mechanical systems defined by a cylindrical chamber filled with balls and/or rocks that rotate around their own longitudinal axis. Due to the action of charges, the lifters/liners wear significantly and their shape will be changed which will influence the efficiency of the mill. Liner bolts are the mill components which connect the mill interior with the exterior environment. With this property, bolts have been paid more and more attention. The first part of the thesis covers the structural analysis of the lifter/liner bolts, and the possibility for on-line charge motion measurement with the aid of bolts is discussed by comparing the strain distributions at the bolt areas where the bolts occupy different mill circumferential positions. In order to measure the lifter/liner wear, a real-time, on-line wear sensor was developed by the Comminution Dynamics Laboratory. However, the positioning of the sensor/sensors affects the strength of the mill is unknown. The second part of the project provides detailed research on this issue by FEA analysis so as to provide a basis for the practical application of this kind of sensors. Finally, during the grinding process of tumbling mills, some mills can vibrate greatly at some ranges of mill rotating speeds and as a result the mills cannot work properly because of this vibration or resonance. With six different mill models, the final part of the thesis investigates the mill natural frequencies and their modes by FEA and furthermore, explores the effect of mill diameter, length on these frequencies and modes.
