Abstract

PURPOSE: To utilize coke powder effectively, and to obtain the titled raw coal having high coke strength, by adding a specific amount of finely pulverized coke powder to a mixed coal.
CONSTITUTION: The objective raw coal is obtained by pulverizing coke powder the size to pass a 35 mesh sieve with a crusher such as a roller mill, and the finely pulverized coke powder is added to a mixed coal in an amount of ≤12%. The roller mill-type crusher is e.g. the one having vertical rollers 2,2 attached to the casing rotatably around the axis 1 and pressed to the surface of the table 5 revolving with a driving mechanism 4. Coke powder is fed to the surface of the table 5, and crushed with the rollers 2,2.
