ratio range for ball mill. autogenous mills range up to meters in diameter the lengthtodiameter ratios in the previous table are for normal applications for primary grinding, the ratio could vary between and for fine regrinding in open circuit, the ratio ranges from to some ball mills are the design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material and the system for discharging the output product. the size of a mill is usually characterized by the ratio length to diameter and this ratio most frequently varies from 0.5 to 3.5. thedec 01, 2013 the total volume of the balls, Al powder, and water reached approximately 60% of the bottle height. five types of ball diameter were used: nominal diameters of and mm. By using the balls with each size, ball mill was carried out for at three different rotation speeds: 50, 100, and 153 rpm.planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel. the direction of movement of the sun wheel is opposite to that of the grinding jars (ratio
