The current invention concerns a method for producing an aqueous dispersion suitable for being used as a flame retardant additive to wood composite panels. Methods are provided that involve providing in a disperser tank having an internal wet-milling system and being externally connected, via an outlet valve, to a second, inline wet-milling system. When an outlet valve is closed, water and flame retardant in the form of granules and/or particles are subject to wet-milling to obtain a premix. A pH-regulator may be adding to the premix with an inorganic thickener, and optionally at least one smoke suppressing agent, while maintaining the actuation of both wet-milling systems until a dispersion is obtained.
