Pulverization behavior was investigated for the blend of subbituminous and bituminous coal by using hammer type pulverizer with rotary classifier. The aim of this study is to predict the pulverization behavior such as the size distribution of pulverized coal at mill outlet and the mill grinding power from coal analysis data. With increasing the blending ratio of subbituminous coal, the size distribution of pulverized coal at mill outlet and the mill grinding power became larger. It is considered that the grindability of blended coal is able to be predicted with weighted average on the individual grindability and the blending ratio of subbituminous and bituminous coal.
