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; and rows of teeth protruding from the front side of the substrate. The rows of teeth are arranged along an arc extending from a first lateral side of the plate segment to an opposite lateral side of the plate segment. A first tooth in the rows of teeth has a first tooth face. A buttress extends from the first tooth face to a face of an adjacent tooth. The buttress has a concave profile at a height above the substrate less than a full height of the teeth.
