THE OPTIMAL BALL DIAMETER IN A MILL

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 …

AMIT 135: Lesson 7 Ball Mills & Circuits – Mining Mill

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,

how many pounds of steel balls are used in a ball mill

Bal-tecBall Weight and Density 4.1887 times the density of lead which is 0.409 pounds per cubic inch gives a weight of 1.713 pounds. What would a three inch diameter lead ball weigh The radius of 1.5 inches cubed equals 3.375 ⋅ 4 ⋅ π = 42.410 divided by 3 equals 14.137 cubic inches times 0.409 (the density of lead) gives 5.782 pounds.
