Mixing process of at least two cohesive powders, apparatus for making this mixing process and use thereof

摘要

The invented mixing process of cohesive finely distributed powders with particle size less than about 10 micrometers is characterized in that the powder mixture being finely distributed on a perforated partition wall of a tank and the tank are brought into rotary motion in vertical plane by an angle of substantially equal to 180 degree at every revolution. The apparatus for making the invented process consists of a tank (2) with at least two compartments (2a, 2b) being separated by at least one perforated partition wall (4), further at least one of these compartments is provided with a means (10) for mixing powders. The apparatus further contains a means for rotation the tank and a vibrating means. The invented apparatus is used for mixing cohesive finely distributed powders.
