The aim of our research was to apply Box-Behnken experimental design and response surface methodology for modeling of some Turkish coals. As a base for this study, standard Bond grindability tests were initially done and Bond work indexes (W-i) values were calculated for three Turkish coals. The Box-Behnken experimental design was used to provide data for modeling and the variables of model were Bond work index, grinding time and ball diameter of mill. Coal grinding tests were performed changing these three variables for three size fractions of coals (-3350 + 1700 mu m, -1700 + 710 mu m and -710 mu m).
