  • Method for operating an agitator ball mill
    Patent number: 8876028
    Abstract: A method for operating an agitator ball mill with a cylindrical grinding container is disclosed. The grinding container includes at least one grinding stock inlet and at least one grinding stock outlet. An agitator shaft connected to a drive is disposed in the grinding container. The agitator shaft transmits a part of the drive energy of the drive to the auxiliary grinding bodies. The auxiliary grinding bodies are distributed loosely in the grinding container. Furthermore, the agitator ball mill includes a separation device assigned to the grinding stock outlet, wherein the separation device is disposed around a rotational axis and/or rotates around this rotational axis. The separation device includes at least two components, whereof one component is at least one separation device and a second component is a dynamic element for generating a material flow.
