Mar 29 2019 to make a ball mill start by building a wooden platform and attaching a motor underneath it then cut a slit into the wooden platform for the belt to pass through and attach casters to the platform for the container to sit on next thread the belt through the slit and position the container so the belt is pulled tight
The ball mill is a tumbling mill that uses steel balls as the grinding media the length of the cylindrical shell is usually 115 times the shell diameter figure 811the feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 2040 water by weight
In order to achieve this the ar tool employs a graphical technique that is defined by a set of preset conditions in this investigation the input variables were the ball and particle size distributions while the output variables were the desired psd the objective function was to maximize material in the specified intermediate size class 2
Effect of ball diameter or rod diameter variation the first relationship to be considered is the effect of the variation of the ball diameter or rod diameter upon the size distribution obtained in fig 61 are shown typical size frequency curves obtained by ball milling these curves being deduced from the data of coghill and devaney
Based on his work this formula can be derived for ball diameter sizing and selection dm 6 log dk d05 where d m the diameter of the singlesized balls in mmd the diameter of the largest chunks of ore in the mill feed in mm dk the p90 or fineness of the finished product in microns umwith this the finished product is
