The ball-to-powder ratio of the milling of Ti andThe operating principle of the ball mill - energosteel,08-02-2017· The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then,Cast Grinding Steel Balls - 911Metallurgist,Secondary Grinding – Ball Mills. In secondary ball milling, abrasive and corrosive conditions predominate. The smaller balls [< 2½”, (65 mm)] typically used in secondary milling environments effectively reduce the impact component of wear to the point where grinding media must be primarily designed to reduce abrasive and corrosive wear.
