When the optimum minimum coal charge crushing level is attained, an increase in the bulk density and a decrease in crushing costs are achieved. As applied to the conditions of the Novolipetsk Metallurgical Association in particular, a decrease in the extent of charge crushing of 1% facilitates an increase in the bulk density of 0.35-0.52%. The optimum minimum crushing level must be selected from the condition for obtaining coke which most fully meets blast-furnace production requirements. Industrial investigations were carried out at the Novolipetsk Metallurgical Association; an optimum coal charge crushing level (differential crushing scheme) for batteries No. 1-4 and 5-8 was selected on the basis of these investigations.
