ABSTRACT:
A process for producing a coal-water slurry having a low viscosity and a good stability even in a high coal concentration without increase in the production cost is provided, which process is characterized in that when coal is fed to a wet mill and milled therein, the coal feed is divided in a multi-stage manner, also in that two coals of different grindabilities are milled together.
