Measurement of Particle Dispersion State in a Solid-Liquid Agitated Vessel using Multi-Points and a Real-Time Method of Measuring Slurry Concentration by Transmitted Light System Mode

Abstract

We developed multi-points and a real-time measuring method of measuring local slurry concentration using transmitted light-system mode in a solid-liquid agitated vessel by applying a real-time digital signal processing system which we produced for trial. By this method it is possible to measure local slurry concentration in the agitated vessel in an extremely short time interval. We defined a coefficient of local concentration variation and an average coefficient of local concentration variation in the vessel, using the measured concentration data, and proposed a method of indicating particle dispersion state in the solid-liquid agitated vessel.
