A continuous process for dispersing a particulate solid material in a liquid comprising the steps of a) dosing a particulate solid material feed stream via a particulate solid feed line (1) into a mixing chamber (2), b) simultaneously dosing a liquid feed stream via a liquid feed line (3) into the mixing chamber (2), wherein at least one of the feed streams additionally comprises an organic film-forming binder, c) simultaneously exerting a shear force on the content of the mixing chamber (2) sufficient to mix the particulate solid material and the liquid to form a mixture of particulate solid in the liquid, and d) simultaneously exerting a shear force to the mixture of particulate solid in the liquid sufficient to reduce the particle size of the particulate solid material in a dispersing chamber (4) to form a particulate solid material dispersed in the liquid, and e) simultaneously removing a liquid product stream of particulate solid material dispersed in the liquid from the dispersing chamber via a liquid dispersion outlet line (5), wherein the mixing chamber (2) and the dispersing chamber (4) are one single chamber (2, 4), wherein the particulate solid material is in the form of powder, granules or pellets.
