Abstract

PURPOSE: To obtain high-quality coke, by crushing raw material coal, separating coarsely granulated coal by a sieve, crushing selectively the separated coal to give blended coal with adjusted particle sizes, blending part of the blended coal with a binder to give bulk coal, blending the bulk coal with the blended coal with its water content controlled to carry out carbonization.
CONSTITUTION: Coarsely granulated coal in raw material coal is separated by a sieve in the crushing process for coal, it is crushed selectively to give blended coal with adjusted particle sizes, and part of the blended coal is blended with a binder to give bulk coal. While, the residue of the blended coal is adjusted to a water content of ≤6wt%, and the bulk coal is blended with the blended coal, and carbonized, to give the desired coal. 1W15wt% bituminous substance is preferably added to the blended coal with its water content adjusted to ≤6wt%. The water content of the bulk coal is preferably adjusted to ≤6wt%.
