摘要： In a process for mechanically cleaning a powder (25), the powder is projected at a predetermined speed and at a determined frequency during a defined time against at least one surface in order to separate therefrom particles of impurities (35) that adhere to its surface. The thus obtained powders (30, 31 and 35) are then sorted according to size. A cleaning device (1) for carrying out the process has a separator (2) mounted upstream of a wind sifter (3) or cyclone (4). A simplified embodiment of the cleaning device (1) has only a wind sifter (3).
