Abstract
PURPOSE: To produce quality granules in a short time, by adding a binder and coal particles or granulated coal particles as a nucleating agent to coal-water slurry and granulating coal with stirring.
CONSTITUTION: A part of a coal-water slurry 8 and a small amount of a binder 12 are supplied to a first agitation tank 9. The mixture is stirred by means of an agitating element 13, whereby the binder 12 is adsorbed by coal particles in the slurry 8 and coal particles are granulated to a particle size of 0.5W1mm, said size showing a quick growth rate of the granule. A slurry 16 contg. the resulting granule is supplied to a second agitation tank 11 containing the remaining part of the coal-water slurry 10 and a binder 14. The mixture is stirred by means of an agitating element 15 to granulate coal particles in the slurry 10 and the resulting granule is recovered in a slurrified stte. Then water is removed from the slurry.
