Patent AT-E401270-T1: [Translated] VIBRATIONAL SCREW CONVEYOR

The conveyor has a driver, a useful mass and a counter mass which can be brought into a mutually oppositely oscillating rotational vibrating movement about a central axis of rotation by the driver. The useful mass and the counter mass are mounted so that they can be moved with respect to one another over spring arrangements which are distributed about an axis of rotation. A portion of the useful mass is a pot which is located detachably and exchangeable. The moments of inertia of the useful mass and of the counter mass are in a defined ratio to one another. The pot, which can be mounted exchangeably, is designed so that the moment of inertia of the useful mass and, with that, the ratio of the moments of inertia remain essentially unchanged. The moments of inertia are identical or that the moment of inertia of the useful mass is larger than that of the counter mass.
