INVESTIGATING THE DIFFERENCES IN CHARGE DYNAMICS DUE TO A VARIATION OF THE INSTRUMENTED BALL PROPERTIES

The validation of charge mill motion simulations is limited by the lack of information from inside a tumbling mill. To this end, an electronic system capable of measuring a number of physical quantities within a highly dynamic environment has been designed, built and tested. Once protected, the system can be used to record physical quantities within a ball mill. Different types of protective shells may be used to protect the electronics. When comparing the measurements recorded using two different shells, some differences in the behaviour of the instrumented ball were observed.
