Optimization of mill performance by using
The pulp density is an important parameter which influences the grinding efficiency. In iron ore, for instance, a variation of 2 to 3% solid content in the slurry could lead to a difference up to 10% on the energy (kWh/T) for a similar grind.

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 …
