A method and apparatus for treating materials or material mixtures in a treatment apparatus operating on the principle of the double-action impact mill, which comprises a discharge conveyor (34), such as a discharge screw. A material layer (40) is maintained between the discharge opening and the discharge conveyor, using the material exiting the outermost ring (16") of the treatment apparatus through the discharge opening (30), which layer prevents free discharge of the material to be treated from the treatment apparatus. |
