ABSTRACT:
A method of producing a thick slurry of powdered coal and water. It includes feeding less coal than is required for the thick slurry into a ball mill, and introducing all of the water required so that a thin slurry is produced. The remaining coal required is pulverized in a dry grinder, and the thin slurry and dry powdered coal are mixed to produce the desired thick slurry.
