The produced flakes have a dimension of a thickness (t) < 0.5 µm and diameters (d) from 20 to 200 µm, consequently a ratio d/t up to 1000. The flake-geometry can be controlled by the variation of process parameters such as rotary speed of the rotor, ratio of powder/ball charge, filling ratio of the system, process temperature and operating model.
