Abstract
A device for mixing, milling or kneading feed materials, such as plastics and fillers, including a pair of plate members, preferably upper and lower discs, each having a non-flat operating surface and being adapted so that, by movement, preferably rotation, of one or both, a relative motion between the two operating surfaces may be maintained, and grooves provided in both of the operating surfaces and arranged so that the grooves of one operating surface may cross the grooves of the other operating surface upon the relative motion between the two operating surfaces.
