SIZE REGULATING METHOD OF MIXING COAL FOR MAKING COKES

摘要

PURPOSE: A size regulating method of mixing coal for making cokes is provided to stably improve the coke intensity even if a plurality of coal kinds is combined through the smashing of each group coal. CONSTITUTION: A size regulating method of mixing coal for making cokes comprises the following steps. The maximum fluidity is measured at a coal classification. The coal kind is grouped based on the maximum fluidity measured at. The coke intensity according to the particle-size fraction is measured at by group less than 3mm. The particle-size fraction range showing the ultimate strength among the coke intensity measured at is established as the particle-size fraction. According to the particle-size fraction instituted as by group, the coal is smashed.
