Laboratory ball mill, particular planetary- or centrifugal force-mono ball mill for crushing and mixing of samples, has carrier device which is rotatably mounted around central axis and grinding station with receiving device

The laboratory ball mill has a carrier device (8) which is rotatably mounted around a central axis and a grinding station (10) with a receiving device (16) for a grinding container (12) filled with grinding stock and grinding bodies. The receiving device is mounted around an offset planetary shaft. A drive is provided for the carrier device and another drive is provided for the grinding station. A clamping unit with a clamping element is provided for axial clamping of the grinding container in the receiving device. The clamping element is arranged in the receiving device below the grinding container and the grinding container is axially clamped from below against an upper stop of the receiving device. Die Erfindung betrifft eine Laborkugelmühle, insbesondere Planeten- oder Fliehkraftkugelmühle im Labormaßstab mit einer Zweipunkt-Lagerung der Mahlstation, einem Käfig zum Einsetzen und Verspannen des Mahlgefäßes, einem Exzenter-Verspannmechanismus für das Mahlgefäß und einem motorischen Antrieb der Verspannung und Verrieglung des Käfigs.
