An operating method for a grinding body mill having a housing which surrounds a grinding chamber in which grinding bodies are arranged and, during normal operation, are set in motion for the purpose of grinding a grinding stock to be ground, which housing includes a product inlet and a product outlet, between which the grinding stock to be ground flows through the moving grinding bodies, wherein, by means of a separating device positioned upstream of the product outlet, grinding bodies are prevented from exiting the grinding chamber into the product outlet during normal operation of the grinding body mill, and wherein furthermore, grinding bodies that have passed through the separating device and onward through the product outlet pass into an upwardly inclined discharge pipe from where, when the grinding body mill is at a standstill, the grinding bodies are directed out of the discharge pipe through the product outlet into a rotor body of the separating device and, when operation of the grinding body mill is resumed, the grinding bodies are conveyed back into the grinding chamber owing to the rotation of the rotor body. The invention also relates to a grinding body mill of the type for carrying out the method. |
