Abstract: The continuously operating stirred ball mill used for finely and very finely milling a material has a cylindrical or conical grinding chamber which has a horizontal axis and in which a stirrer rotatable about the chamber axis and intended for moving grinding media present in the grinding chamber is arranged. The known stirred ball mills have the disadvantage that the grinding media are entrained in the direction of the outlet by the material stream passed through from the inlet to the outlet, with the result that said grinding media accumulate in the region of the material outlet and thus lose their grinding effect and adversely influence the milling process. In contrast, the stirrer of the ball mill according to the invention has paddlewheel-like stirring members or propeller-like stirring members formed with separating and guiding disks.
