1. A plate segment comprising:
a substrate having a front side and a back side, wherein the back side is configured to be mounted to a support disc of a disperser; and
rows of teeth protruding from the front side of the substrate, wherein each of the rows of teeth are arranged along an arc extending from one side of the plate segment to an opposite side of the plate segment,
wherein in at least one of the rows of teeth, adjacent teeth are joined by a bridge spanning a gap between the adjacent teeth, wherein the bridge has a cross-sectional shape comprising one of a circular shape, an oval shape, a teardrop shape, or a wedge shape, and
wherein the bridge is elevated above the front side of the substrate such that the bridge is separated from the front side by an open space in the gap.
