Abstract
PURPOSE: To reduce the carry-over sharply in charging a dried coal into into a coke oven, by classifying the coal selectively according to the grain size thereof, kneading the resultant fine granular coal with an additive, and mixing the kneaded coal with the remaining coarse coal.
CONSTITUTION: A coal after a preheating column 2 is classified into a coarse granular part in the primary separating apparatus 7 and then into a fine granular part in the secondary separating apparatuses 8. The fine granular part and dust from a dust collector 13 are fed into a premixer 15, mixed with an additive sent from an additive tank 17 by a pump 18 and then introduced into a mixer 16. The coarse granular part separated from an air current by the primary separating apparatus 7 is newly mixed with the resultant mixture in the mixer 16, and fed to a coal preheating tank for a coke overn by a conveyor 19 and then charged into the coke oven.
