Description

technical field [0001] The invention belongs to the technical field of metal powder processing, in particular, the invention relates to a screening and drying device for metal powder. Background technique [0002] Metal powder is generally obtained by ball mill grinding for a certain period of time. During grinding, metal and water are mixed into the ball mill, and then the ball mill is started to crush the metal by the grinding body. The crushed metal powder needs to be dehydrated. The dehydrated powder needs Screening, the traditional screening equipment directly pours the powder into the vibrating screen, without considering the influence of the weight of the metal powder on the screen, too much powder, the screen is under too much pressure, the aperture is enlarged, and the screening effect is reduced , too little powder, the screening efficiency is reduced. [0003] The existing patent 204584279 discloses a metal powder crushing and screening device belonging to the te...
