ABSTRACT:
A process for producing a coal-water slurry of low viscosity and high coal concentration with a low specific energy and a good efficiency is provided, which process comprises wet-grinding coal by means of a wet vertical ring-roll mill in the presence or absence of a surfactant and recycling a part of the coal ground by the mill, as it is, without classifying it, to the mill through a splitter.
