A feeding device intended for refiners with two opposed refining means (11,12), of which one is stationary and one rotary. The refining means are provided with refining elements (14,15), which between themselves form a refining gap (17) with a refining zone (16) for working lignocellulosic fibrous material. The feeding device (22) comprises a circular disk (23) with at least one strip (24), which extends from a position close to the centre of the disk radially outward to the circumference of the disk. This strip (24) along the greater portion of its upper edge is provided with a roof (25) projecting out symmetrically on both sides of the strip. The feeding device (22) is intended to be placed centrally on the rotary refining means (12) with the strip (24) facing to a central material feed opening (19) in the stationary refining means (11).
