Abstract:
1. Method for dispersing a water-soluble polymer having a standard grain size distribution of between 0.15 and 1 mm, comprising: metering and prewetting polymer with primary water in a wetting cone connected to a primary water inlet circuit; grinding and draining dispersed polymer in a chamber located at a bottom end of the cone, the chamber including a rotor driven by a motor and equipped with knives, and a fixed stator having blades; providing a peripheral ring fed with secondary water by a secondary water circuit on all or part of a periphery of the chamber surrounding the stator; and propelling pressurized secondary water through perforations in the ring onto the blades of the stator and thereby releasing ground and swollen polymer on a surface of said blades.
