Abstract: A refining system and process using a specially designed stator refiner plate that includes a major refining surface comprising a series of bars and grooves, the bars include a leading surface that comprises an irregular surface hosting a series of protrusions extending along the bar, and a trailing surface that is relatively smooth compared to the leading surface that lacks an irregular surface.

Abstract: A refining system and process using a specially designed stator refiner plate. The specially designed stator refiner plate includes a major refining surface having a series of bars and grooves, the bars include a leading surface having an irregular surface. The irregular surface hosts a series of protrusions extending along the bar. The bar further comprises a trailing surface that is relatively smooth compared to the leading surface. The trailing surface lacks an irregular surface.
