Coal Preparation an overview ScienceDirect Topics

Coke properties are determined by various factors beside homogeneity of the coal mix. The major factors are crushing fineness, oiling, preheating, and pre-briquetting. Keeping in mind the petrographic non-uniformity, high ash and high hardness of Indian coal, selective preparation of coal by pneumatic separation was envisaged.
