Abstract
The present invention relates to a method of producing compression molded coal to be used for the block charging for the coke oven operation wherein the raw material coal are initially compression molded, a part of said already compression molded coal is caused to remain in the molding box while the subsequent raw material coal is charged to be compression molded, and said compression molded coal is combined so that the compression molded coal may be produced continuously. At the compression molding, the already compression molded coal may overcome the compression force applied to the subsequent compression molded coal due to its friction generated between the molded coals and the molding box. Further application of pressure to the pressing plate after the molding operation will cause the compression molded coal to be pushed out of the molding box.
