Milling and Mixing in the Materials Characterization Lab
The attritor mill is a wet grinding attrition mill. It differs from conventional ball mills as it uses much smaller media with diameter less than 5mm, leading to greater media-material contact area. Additionally, the attritor mill works at a higher rotation speed up to SPEED.
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 feed calculation.
