A theoretical formula predicting the slurry residence time of deep cone thickener is derived. A method of calculating the internal slurry volume of the deep cone is presented. A rheometer was used to measure the critical mass fraction of the paste and then a homemade deep cone simulator was used to identify the densification time for the slurry to reach a critical mass fraction. The static settlement slurry mass fraction was also measured. These parameters were applied to calculation of the internal slurry volume. A deep cone thickener from an Inner Mongolian mine was used to verify the methods. The results showed that internal slurry volume of the deep cone thickener was 9 322.77 m3 by our method compared to an actual slurry volume of 9 306.57 m3. There is a 16.20 m3 difference between these values for a 0.17% difference. Source
