Abstract
An assembly for the production of dispersions including a mixing unit (7) and a circulation tank (1) for holding liquid, the mixing unit (7) including a first solid inlet (8) 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 (13), the liquid inlet is fluidly connected to the circulation tank (1) such that liquid in the circulation tank flows to the mixing unit (7) via a circulation tank outlet (4), the return outlet (15) transferring the combined liquid and solid from the mixing chamber (7) into the circulation tank (1) 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.
