Claims18
A deflaker plate for a deflaker machine, the deflaker plate comprising:
- a substrate including a surface;
- and
- a plurality of teeth extending from the surface of the substrate,
- wherein a specified number of teeth of the plurality of teeth each comprises a serrated face,
- wherein serrations on the serrated face have peaks and valleys,
- wherein each of the peaks and valleys are directed across the serrated face in a direction of rotation of the deflaker plate, and
- wherein each of the peaks and valleys are oriented to either be parallel with the surface of the substrate or define an acute angle relative to the surface of the substrate.
