Abstract: Within a loose or bulk good container there is arranged a loosening wheel which is wider than a discharge spiral. The loosening wheel is secured by a wheel holder device at a removable wall portion of the container. The removable wall portion is arranged transversely with respect to the discharge spiral and is fixedly connected with an outlet or discharge connection of the container. During exchange of the discharge spiral and/or the loosening wheel there can be removed as a structural unit or assembly from the container wall the removable wall portion together with the outlet or discharge connection, the wheel holder device and the loosening wheel, and such structural unit can be replaced by a different structural unit containing the corresponding elements but of different dimensions.
