Latest Patents

Hemmings' latest patents include a method and device for determining rheological properties. This invention focuses on the measurement of rheological properties of high-density slurry materials, specifically high-density mill tailings. The method involves placing a sample of the tailings within a mixing tub, utilizing either a concentric paddle or a planetarily movable paddle for effective mixing. A digitally controlled electric motor drives the paddle at a constant or predetermined speed. The tub is designed to pivot laterally against a load cell, allowing for direct determination of reaction torque, which correlates to viscosity and other rheological properties of the mill tailing.

Another patent by Hemmings also addresses the measurement of rheological properties using a mixing paddle and a digitally controlled electric motor. Feedback control elements, including a variable speed drive and a computer, monitor the mixing speed and adjust for any deviations. The load cell emits signals that are processed by the computer, which correlates torque to speed and determines rheological properties in real-time. This innovative approach allows for continuous monitoring and comparison of torque/speed parameters to stored rheological properties of known materials.
