how to calculate alumina ball charge for dry mill

Apr 15 2014 Aluminum 400 With carbide endmills multiply those settings by 3 as a starting point so SFM with Carbide Endmills Stainless Steel 120 Mild Steel 300 Brass 900 Aluminum 1200 Then RPM 4 x SFMDiameter Now to find your feed first calculate your chip load A reasonable starting point for the chip load is to divide your endmill diameter by 200

    Optimum choice of the makeup ball sizes for maximum

    Sep 01 2013 For the same amount of ball charge the number of balls in the mill decreases as the ball size increases Thus the S values are lower for larger balls However larger balls are capable of breaking large particles therefore the size at which the S value becomes maximum x m increases as the ball size becomes larger
