Abstract

The grinding efficiency of circuits using tumbling media mills in closed circuit with hydrocyclone classifiers may be improved by control of the mill slurry rheology. The rheology affects both the rate of fine material production by the grinding mill, and the separation performance of the hydrocyclone. In addition, the manner in which rheology changes are produced will affect hydrocyclone performance. This parameter is neglected in process control situations due to the difficulty of making rheological measurements of dense slurries on-line. In recent years, a number of new viscometers has been developed which may be useful for this purpose.
