The invention relates to a deviation ring for paste comprising an annular rebound wall (2) for a self-distributing centrifuge (1). The invention also relates to a corresponding self-distributing centrifuge (1). In the deviation ring, the angle of incidence ? of the tangents of the rebound wall (2) of the deviation ring (4), opposite the distribution slit (3) of the centrifuge (1), in relation to the horizontal, is between 3 and 60° over the entire opening width of the distribution slit (3).
