Experimental Investigation on Relationship between Sedimentation Rate Constants of Solid Materials

Abstract

It has been fount that the sedimentation process is a rate-governed process, which is a combination of a constant rate and falling rate. The various solid materials like Silicate, Calcium Carbonate, and Barium Carbonate were taken and ground in prototype ball mill and sieved to different size fractions and different consistence sedimentation tests were conducted. In this study, an attempt has been made to draw some correlations between sedimentation rate constants (overall sedimentation rate constant (Ko), sedimentation rate constant for constant rate period (Kc) and falling rate constant (Kf)). Variation of Ko on various particle sizes and slurry consistency has also been reported in this work.
