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.,

Variables in Ball Mill Operation Paul O. Abbe®

Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art it’s just physics. The formula for critical speed is CS = 1/2π √(g/(R-r) The principle of mill operation is the impingement of the solids between pieces of media. The majority of media motion and milling occurs on the
