A method for dosing and particularly for mixing substances, particularly for mixing at least one granular or powdery solid matter with a liquid. A first substance, particularly the granular or powdery solid matter is liquidized by means of a gas fed continuously or pulsatingly, and after that this homogenized gas/matter mixture is brought together in a time stable, dosed manner and mixed with a second substance, particularly a liquid. For dosing the homogenized gas/matter mixture, there is additionally supplied to it gas prior to the mixing with the second substance, with this gas being supplied to the gas/matter stream in a sheathing way and parallel to its direction of flow.
