Abstract: The specification describes a tube mill for the comminution of refuse and her waste materials, consisting of a rotary tube body with an axially arranged material inlet and material outlet in the case of which the tube body is partly filled with grinding bodies. The diameter of the tube mill is two to three and a half times greater than the length of the tube mill with respect to that part of the tube mill, which has a cylindrical tube form, and furthermore the clearance diameter of the inlet opening amounts to at least 25% of the clearance mill housing diameter. Furthermore, the outlet duct is provided at the inner walls with helically arranged baffle surfaces.
