A mixing machine, especially for liquids, in which the material to be mixed is fed under pressure between two relatively rotatable abrasive elements (24, 26), one having a central aperture to enable the material to be worked upon in a gap (41A, 41 B) between the two elements, the size of said gap diminishing from the central aperture to the periphery of the elements from which the mixed material emerges.
