1. A refiner comprising:
- a rotor disc including a rotor plate having concentric rows of rotor teeth;
a stator disc opposite to the rotor disc, wherein the stator disc includes a stator plate;
the stator plate includes concentric rows of stator teeth intermeshing with the rows of rotor teeth;
the rows of stator teeth include an outer row of stator teeth having leading sidewalls angled to deflect particles flowing between the teeth of the outer row, andthe rows of stator teeth include an inner row of stator teeth that are radially inward of and adjacent the outer row, wherein the stator teeth in the inner rows have leading sidewalk parallel to a radius of the stator plate.
