Abstract
PURPOSE: To increase deashing rate, by crushing an obtd. granulated coal followed by water washing in granulation/deashing of coal by adding a binder to an aq. slurry of a fine coal powder followed by agitation.
CONSTITUTION: A soln. 26 to be granulated obtd. by adding a small amt. of an oil as a binder to an aq. slurry of a fine coal powder is supplied to a granulator 21 and the fine coal powder is granulated with agitation and deashing (mark 22 shows a stirring blade; 23 a baffle). Then the obtd. slurry of the granulated coal is sent to a crushing vessel 31, where the granular coal is washed by supplying water via a valve 30, and the waste washing water is discharged together with ash via a valve 37. Then after the granular coal in the vessel 31 is crushed to a particle size of about 0.1mm by rotating a stirring blade 31 for crushing, the crushed granular coal is washed by supplying water via the valve 30 and discharged together with an ash deposited in the liquid via the valve 37, to obtain a deashed coal of low ash content.
