A vibration mill is a size reduction equipment that applies the process of continuous impaction in carrying out its size reduction function. The grinding container is made up of a tube that is held in a frame that is supported by means of springs which is filled to approximately 80% total volume with porcelain or stainless steel balls.
The Ernest Henry SAG mill (11 MW) is currently the largest twin pinion single drive mill installed in Australia. Problems have been experienced with the twin pinion drive at Fimiston and with the ring motor at Cadia. At Cadia, excessive vibration and deflections in the drive stator were encountered during
