Design Of Copper Mill Parameters
Milling Parameters
The end mill speed is calculated with the following formula: n [rpm] = (vc [m/min] *1000) / 3.14 * ø d1 [mm]) Example calculation: vc = 500 m/min (selected from chart) d = ø 8 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 …

The ball mill speed was constantly set at 76.8% Cs. Experiments were conducted at different ball sizes (between 20 and 40 mm), grinding time (10–30 min), solids content (65–80%) and work index of copper sulphide ore (12–15.4). RSM and Box–Behnken design were used for the experimental design and modeling of these variables.

The selection function parameters, on the other hand, led to diverging patterns: two parameters ( α and Λ) were not affected by mill design and milling conditions while the other two (i.e. a k and μ k) were more so. Furthermore, variations of parameters a k and μ k with mill diameter were successfully modelled.
