  • The Main Faults In Operation Of Ball Mills And The

    The Main Faults In Operation Of Ball Mills And The

    The ball impact energy on grain is proportional to the ball diameter to the third power 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet dry). None of the characteristics of the material being ground have any influence on K 1.The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills energy efficient grinding machines. Vertimill energy savings can range from 30 to greater than 50 compared with traditional mills, and the SMD energy savings can be far greater than 50 of ball mill energy in fine grinds.
