See Details2) Ball milling – a ball mill with a diameter of2.44 meters, inside new liners, grinding wet in open circuit. When the grinding conditions differ from these specified conditions, efficiency factors (Rowland and Kjos, 1978) have to be used in conjunction with equation 1.
See DetailsMilling Speed andFeedCalculator Determine the spindle speed (RPM) andfeed rate(IPM) for a milling operation, as well as the cut time for a given cut length. Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an endmillor facemill.
See DetailsUse the RPM, IPT, CLF and the number of flutes to calculate thefeed rateor IPM. If you want to be conservative, choose a slightly lower SFM, but always choose the recommended FPT.
