Abstract
A device for dispersing a water-soluble polymer in powder form having a standard particle size of less than 1 mm, includes: a wetting chamber, a chamber for grinding and discharging the dispersed polymer with a horizontal axis of revolution, and a mechanism for connecting the wetting chamber to the grinding chamber in the form of an L-shaped tube. The upper and lower parts of the wetting chamber and the L-shaped tube have an internal surface with an identical surface tension (TS). The cover of the wetting chamber has an internal surface with a surface tension (TS) higher than the surface tension (TS) of the internal surface of the upper and lower parts of the wetting chamber and the L-shaped tube.
