description | The wet grinding characteristics of CWM (Coal Water Mixture) at high concentrations was investigated by conducting batch preparation tests using a laboratory-scale ball mill. Although the grindability became worse with the increase in the slurry concentration, it was found possible to prepare CWM of 65∼75% by use of the proper dispersant. The improvement of grindability was caused by the improved movement of balls owing to the decrease in the apparent viscosity at low shear rates. The grindability greatly changed with the coal type. The difference of grindability among coal types was mainly due to the difference in the flocculation force.† This report was originally printed in KAGAKU KOGAKU RONBUNSHU, 14(2), 155-160 (1988) in Japanese, before being translated into English by KONA Editorial Committee with the permission of the editorial committee of the Soc.
