A method of homogeneously mixing particulate material by means of a mixing machine which has two counter-rotating shafts provided with blades disposed at an angle to and parallel with the shafts, such that by giving the blades a specified velocity and at a specified filling level, a circulating movement of materials in the plane of the shafts is obtained, as well as a lifting of the material between the shafts into a whirling, floating zone in which the mixing takes place. |
