Abstract
The present invention relates to a centrifugal-force vibratory grinding machine having a container (3) which receives filling material consisting of workpieces and work bodies and the bottom (4) of which rotates relative to the container wall (5) around the axis of the container and leaves a separating gap (7) towards the container wall (5), and it proposes, in order to reduce the wear within the region of the separating gap (7), that at least one discharge element (A) is provided for the removal of particles of filling material which have penetrated into the space of the gap, which element engages into the space of the gap and rotates with the bottom (4) and/or is stationary with respect to the container wall (5).
