    11/1/2020· In this study, considering different operational parameters for stirred media mill, change in specific energy was compared to the change in R x values, i.e. the cumulative weight of the material undersized to a specific sieve. R values, namely R 38, R 75, R 106, were measured before and after grinding in stirred mill.The change in R x (ΔR x, %) values were calculated and they were used to

  • Milling Parameters

    The end mill speed is calculated with the following formula: n [rpm] = (vc [m/min] *1000) / 3.14 * ød1 [mm]) Example calculation: vc = 500 m/min (selected from chart) d = ø8 mm 19904 rpm = (500 *1000) / (3.14 * 8). If the maximum speed of the milling motor is lower than the calculated value, the maximum speed of the milling motor needs to be inserted into the formula for the feed calculation.
