Ball Mills Mine Engineercom A ball mill grinds material by rotating a cylinder with steel grinding balls causing the balls to fall back into the cylinder and onto the material to be ground the rotation is usually between 4 to 20 revolutions per minute depending upon the diameter of the mill the larger the diameter the slower the rotation Mill Critical Speed Calculation Effect ofmill speedon the energy input in this experiment the overall motion of the assembly of 62 balls of two different sizes was studied themillwas rotated at 50 62 75 and 90 of thecritical speed six lifter bars of rectangular crosssection were used at equal spacing the overall motion of the balls at the end of five revolutions is shown in figure 4 as can be seen from the Amit 135 Lesson 7 Ball Mills Circuits Miningmill Describe the componentsof ball mill explain their understandingof ball milloperation explain the role ofcritical speedand power draw in design and process control recognize important considerations inball millselection reading lecture inball mills steel balls or hard pebbles to break particle based on impact and attrition Ball Millobjective To Determine The Acritical Ball millobjective to determine the acritical speedb actualspeedc optimumspeedd reduction ratio e constants for i rittingers law ii kicks law iii bonds law equipment and materials requiredball mill sieves weight balance brick theory theball mill
