A vibrating spiral conveyor includes a vibrating system with 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 over at least one driving device. 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 the axis of rotation, a portion of the useful mass being a pot, which is disposed detachably and exchangably. The moments of inertia (MN, MG) of the useful mass and of the counter mass are in a defined ratio to one another and the pot, which can be mounted exchangeably, is designed so that the moment of inertia (MN) of the useful mass and, with that, the ratio of the moments of inertia (MN, MG) remain essentially unchanged.
