THE EFFECT OF OVERLOADING AND PREMATURE CENTRIFUGING ON THE POWER OF AN AUTOGENOUS MILL

Load behaviour in an industrial mill has been measured directly by inserting probes through liner bolts. The data from conductivity probes have indicated the presence of premature centrifuging during manipulation of the load mass. Overloading conditions were also encountered. Overloading and premature centrifuging both reduce the power drawn by the mill. These effects have been successfully modelled.
