An assembly for the production of dispersions including a mixing unit () and a circulation tank () for holding liquid, the mixing unit () including a first solid inlet () for receiving a solid, a second liquid inlet for receiving the liquid, a mixing chamber where the liquid and solid are mixed, and a return outlet (), the liquid inlet is fluidly connected to the circulation tank () such that liquid in the circulation tank flows to the mixing unit () via a circulation tank outlet (), the return outlet () transferring the combined liquid and solid from the mixing chamber () into the circulation tank () via a circulation tank inlet. The circulation tank has an interior height which is configured such that a chamber exists inside the tank above the level of the liquid. Alternatively, the circulation tank inlet is permanently positioned above the liquid level or it includes a pipe configured such that the dispersion forms a film on its inner surface. Alternatively, the circulation tank includes an impeller having a diameter equal to or greater than 0.5 times the internal diameter of the tank.

Assembly for the production of dispersions

The present invention relates to the production of dispersions and is particularly suitable for making dispersions with a viscous or solid dispersed phase in a continuous phase with a lower viscosity.
