Title:
PREPARATION OF LOW-VISCOSITY COAL-WATER SLURRY
Document Type and Number:
Japanese Patent JPS608393
Kind Code:
A
Abstract:
PURPOSE: To obtain low-viscosity coal-water slurry having high concentration by simple operation, suitable for transportation and storage, by crushing coal in wet state in the presence of highly concentrated coal, adding water to the prepared slurry.
CONSTITUTION: Coal is crushed in wet state by a ball mill, etc., to give highly concentrated coal-water slurry having preferably 70W80wt% (most preferably 75W80wt%) concentration.
