The ball-to-material ratio was set at 15:1, using 3 mm stainless steel balls, and the ball mill ran at alternating speeds of 900 RPM and 1000 RPM with a grinding time of 5 h. Circulating cooling water was used during the ball milling process to maintain the temperature of the ball milling chamber around 35 °C.
Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding.
