Calculate and Select Ball Mill Ball Size for Optimum Grinding
Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^05 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 (um)with this the finished product isBall Mill Volume Loading Free download as Excel Spreadsheet (xls), PDF File (pdf), Text File (txt) or read online for free Calculate the volume loading for ball mills from internal millBall Mill Volume Loading | Volume | Physical Quantities
