Blade element for a conical portion of a stator

摘要

A blade element (20) for a conical portion (4) of a stator (2) of a refiner (1). The blade element (20) comprises a feed end (24), a discharge end (25), and a refining surface (21) which comprises a feed zone (26) at the feed end (24) of the blade element (20). The feed zone (26) of the blade element (20) comprises at least one guide groove (29) extending from the feed end (24) towards the discharge end (25) for guiding a flow of material to be refined from the feed end (24) towards the discharge end (25). The depth of the guide groove (29) is arranged to change in a direction transverse in relation to the extending direction of the guide groove (29).
