Abstract
A method and device for the measurement of rheological properties of high density slurry materials and in particular high density mill tailings. A sample of the tailings is placed within a mixing tub, with either a concentric paddle or a planetarily movable paddle used to effect the mixing. A digitally controlled electric motor is used to directly drive the paddle at a constant or predetermined speed or speeds. The tub is laterally pivotable against a load cell for a direct determination of reaction torque with correlation to viscosity and other rheological properties of the mill tailing.
