Abstract (en)

[origin: CA3181976A1] A device for dispersing a water-soluble polymer in powder form having a standard particle size of less than 1 mm, comprising: - a wetting chamber (1), - a chamber (8) for grinding and discharging the dispersed polymer with a horizontal axis of revolution, - a means (2) for connecting the wetting chamber (1) to the grinding chamber (8) in the form of an L-shaped tube, characterized in that the upper and lower parts of the wetting chamber (1) and the L-shaped tube (2) have an internal surface with an identical surface tension (TS1), and in that the cover (5) of the wetting chamber (1) has an internal surface with a surface tension (TS2) higher than (TS 1).
