Abstract
A plate segment includes 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; rows of teeth protruding from the front side of the substrate, wherein each of the rows are arranged along an arc extending from one side of the plate segment to an opposite side of the plate segment. In at least one of the rows of teeth, adjacent teeth are joined by a bridge spanning a gap between the adjacent teeth. 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.

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 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.
A disperser plate segment comprising:
- a substrate;
- rows of teeth protruding from the substrate, wherein each of the rows of teeth are arranged along an arc extending from one side of the disperser plate segment to an opposite side of the disperser plate segment;
- and
- bridges between at least some adjacent teeth,
- wherein in at least one of the rows of teeth, the bridges span gaps between the at least some adjacent teeth, and
- wherein the bridges join the at least some adjacent teeth and are elevated above the substrate such that the bridges are separated from the substrate by open spaces in the gaps.
A disperser plate segment comprising:
- a substrate configured to be mounted to a support disc of a disperser;
- rows of teeth protruding from a front side of the substrate;
- and
- bridges between at least some adjacent teeth in at least one of the rows of teeth,
- wherein the bridges join the at least some adjacent teeth and are elevated above the substrate such that the bridges are separated from the substrate in open spaces in gaps between the at least some adjacent teeth by a distance in a range of 30% to 90% of a tooth height.
