Evaluation of the effects of coal grinding in terms

Preparation of sustainable, high concentrated CWS fuel coal is promoted by the hydrophobic nature of the coal surface, characteristic for coals of higher coalification. A great technological problem is to obtain a highly concentrated coal slurry fuel from less coalified hydrophilic steam coals. The paper presents the results of lab scale research on the CWS prepared from Polish steam coal by

COAL GRINDING AND DRYING IN CEMENT

The preparation of coal in cement works comprises the grinding and drying of raw coal delivered to the works. In cases where the coal consumption rates are high and coal from different sources are used, it is advantageous to blend the various coals in conjunction with stockpiling so as to obtain a fuel that is physically and chemically as closely uniform as possible and thus, to achieve well - balanced kiln
