Abstract (en)

[origin: ES8201438A1] The present invention relates to a process and a device for the preparation of fine and uniform dispersions of a divided product in a liquid. A powder and a liquid are fed at a constant flow rate into the device at separate points, and are instantaneously and independently brought up to speed and then brought into contact with each other in a dynamic manner. The process is carried out by means of a turbine composed of at least two non-continuous parts which do not allow the products to return to the center of the turbine, two separate pipes, namely a feed pipe for the powder and a feed pipe for the liquid, and a discharge pipe for the dispersion. The invention applies particularly to liquids possessing a high solvating power with respect to the powders with which they are to be mixed.
