Optimum Choiceof The Makeup Ball Sizesfor Maximum Sep 01 2013 for a single size of makeup ball the mass fractions in the mill within the size ranges are calculated from 11 m k d k u 4 d k l 4 d max 4 d min 4 where d k u and d k l represent the upper and lower boundaries of the ball size interval k d max is the largest ball size in the mill and d min is the smallest ball size in the mill which is still retained is a constant which relates Amit 135 Lesson 8 Rod Mills Miningmilloperator Training Reduction ratio 2 20 depending on material typically r 8 rod mill charge typically 45 of internal volume 35 65 range bed porosity typically 40 height of bed measured in the same way as ball mills bulk density of rods 625 tonsm3 in wet Crusher Reduction Ratio Mineral Processing Metallurgy What is the impact of thecrusher reduction ratioon crusher performance Ball Mills An Overview Sciencedirect Topics In generalball millscan be operated either wet or dry and are capable of producing products in the order of 100 m this representsreduction ratiosof as great as 100 very large tonnages can be ground with theseball millsbecause they are very effective material handling devicesball millsare rated by power rather than capacity

Calculation Of The Ball Mill Reduction Ratio Me Mining Calculation of the ball mill reduction ratio henan 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 ie live chat Calculateand Selectball Mill Ballsize For Optimum Grinding In grinding selecting calculate the correct or optimumballsize that allows for the best and optimumideal or target grind size to be achieved by yourball millis an important thing for a mineral processing engineer aka metallurgist to do often theballused inball millsis oversize just in case well this safety factor can cost you much in recovery andormill Amit 135 Lesson 7 Ball Mills Circuits Miningmill Wet ball mill kg kwh 016a i0015 033 dry ball mill kg kwh 0023a i 05 replacement ball size rowland and kjos proposed the use of their equation for the determination of the initial and replacement media size azzaroni 1981 and dunn 1989 recommended the use of the following expression for the size of the makeup media
