In this study, the grinding conditions in the preparation of coal-water slurries were improved by the use of the dispersing agents PSS and NSF and viscosity values much less than 1000 mPa were obtained. Under the optimum concentrations (0.3% and 0.7% PSS to mass of coal) attainable in the presence of PSS and NSF, it was observed that the conservation of energy would be 70% with coal from Zonguldak and 60% with the one from Istanbul if PSS were present in the grinding medium. On the other hand, the values obtained in the presence of NSF were 45% and 47%, respectively.
