1. A refiner comprising:
- a rotor disc including a rotor plate including 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, and 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.

12. A method of refining celluosic fiber material between opposing discs in a refiner comprising:
-
feeding the fiber material to between the discs;
rotating at least one of the discs to propel the fiber material radially outward and between the discs;
refining the refining material by passing the material through rows of intermeshing teeth on the opposing discs; and
deflecting the refining material as the material flows through an outer row of teeth on one of discs, wherein the teeth in the outer row have a leading sidewall angled to deflect pulp material moving radially between the teeth. - View Dependent Claims (13, 14)

15. A method of refining material between opposing discs in a refiner comprising:
-
feeding the refining material to an inlet of at least one of the discs;
rotating one disc with respect to the other disc while pulp material moves radially outward and between the discs due to centrifugal force;
refining the refining material by passing the material through rows of intermeshing teeth on the opposing discs;
deflecting the refining material as the material flows through an outer row of teeth on one of discs, wherein the teeth in the outer row each have a leading sidewall angled to deflect pulp material moving radially between the teeth. - View Dependent Claims (16, 17, 18, 19, 20)
