Abstract
A method of refining celluosic fiber material between opposing discs in a refiner including: 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.
