quantities of 50, 100, 150, 200 & 300 g. respectively and fed to the ball mill half filled with the grinding media of one inch steel balls counting 100 in number [6]. The open end of the mill was closed by clamping the lid tightly to the mill so that no leakage of the material takes place during grinding operation.
