Abstract
A disperser plate segment for removing contaminants from fiber stock, the segment comprising: radially inner and outer edges, multiple radially concentric rows of teeth, each row of teeth having multiple teeth defining multiple channels disposed intermediate the teeth, each of the channels having a lower channel base surface and each of the teeth having a top surface, at least one face surface extending from the channel base surface to the top surface, and wherein at least one of the face surfaces comprises at least two grooves.

A disperser plate segment for removing contaminants from fiber stock, the segment comprising:
- radially inner and outer edges;
- multiple radially concentric rows of teeth;
- each row of teeth having multiple teeth defining multiple channels disposed intermediate the teeth;
- each of the channels having a lower channel base surface and each of the teeth comprising:
- a top surface,
- at least one face surface extending from the channel base surface to the top surface;
- and
- wherein at least one of the face surfaces comprises at least two grooves.
A disperser plate segment for removing contaminants from fiber stock, the segment comprising:
- radially inner and outer edges and a plurality multiple of radially concentric rows of teeth;
- each row of teeth having multiple teeth defining multiple channels disposed intermediate the teeth;
- each of the channels having a lower channel base surface and each of the teeth comprising:
- a top surface,
- at least one face surface extending from the channel base surface to the top surface, the at least one face surface defining at least two grooves at an angle θ relative to the vertical axis of the face surface.
A disperser plate comprising:
- multiple radially concentric rows of teeth, wherein each row is configured to mesh between rows of teeth on an opposing plate;
- adjacent teeth of the radially concentric rows defining channels between the adjacent teeth, wherein the channels each are aligned with a respective row of teeth on the opposing plate, and
- multiple grooves on a face surface of each of the teeth in at least one of the concentric rows.
