Description
Some flow properties of a cement mill have been determined using radio-tracing with liquid tracer Gold chloride, AuCl-198. Analysis of the response curve with appropriate software indicated an experimental mill mean residence time of 833.4 seconds. The experimental Peclet number calculated as a function of the mean residence time and the variance was 1.65E-3 corresponding to a dispersion coefficient of 0.8 m2/s. The dispersion of the flow was further investigated by curve-fitting the experimental results with the simple axial dispersion model. A mean residence time of 967 seconds and a Peclet number of 30 gave the best fit with a diffusivity of 5E-4 m2/s .
