Effect of the Type and Particle Size of Coal on Inhibitory Influence for Coking Coal by Semi-soft Coking Coal

Recently, the environment has indicated an increase in price of coking coal. Thus, order to produce high strength coke at a low production cost, application blending technology various types coal is required. Coal dilatation important factor determining strength. It well known that dilation values blended containing semi-soft coals does not match with weighted average value and coal; it denotes lower than value. Therefore, this study, develop apply coal, we investigated inhibitory influence kind particle size on hard
