Liquid Handling/Analysis Go with the Flow Why use rheology in mining? In the mining industry, the processing and transport characteristics of slurries are heavily dependant on their rheological properties. Knowledge of rheological parameters such as yield point and viscosity is, therefore, essential when transporting a large amount of slurry. A nton Paar’s range of rheometers include: The Slurry rheometer system This system is based on the Rheolab QC, which is a robust, high precision rotational rheometer. This system allows for the comprehensive characterisation of slurries. The system is capable of measurements according to ISO 3219 as well as sedimentations free measurement with a special vane measuring system. It can be combined with an active temperature control. A Slurry software package allows easy operation with automated routines for flow and viscosity curves, thixotropy measurements, yield stress calculations and r
