Abstract
A ball mill is a type of grinding equipment and used widely in mineral and chemical processing industry because of the simple structure and the ability to grind material finely. Hard balls are placed into a mill cylinder with material to be ground, and the mill is rotated. The vibration and radiated sound of an operating mill can provide a significant amount of information about the operating mill. Therefore, there is possibility to estimate the diameter of the material particle from the measurement data of the vibration and the radiated sound. In this study, we examine the influence of the size and the properties on the vibration and sound with a simulation. As the result, the decrease in the material particle size reduces the vibration and sound pressure. Moreover, the mechanical property of the grind material affects the vibration and sound pressure. These results show that the change of the material particle size and property influences the response of the vibration and sound pressure.
