Feeding elements are disclosed for use in connection with refiners for lignocellulosic fibrous material including a stationary refiner, a rotary refiner mounted for rotation in juxtaposition with the stationary refiner thereby forming a refining gap therebetween, a feeder for feeding the lignocellulosic fibrous material centrally to a central feed zone within the refining gap and a refining zone extending radially outward from the central feed zone, the feeding element including a disk for mounting on the rotatable refiner at a central location in the central feed zone, the disk including at least one radially projecting strip extending from the central portion of the disk towards the outer circumference of the disk and including a body and a projecting portion extending laterally from the body at a location displaced from the upper surface of the disk for a major portion of the radially projecting strip.

Feeding device for fibrous material

A feeding element is disclosed for use in connection with a refiner for lignocellulosic fibrous material including a stationary refiner, a rotary refiner mounted for rotation in juxtaposition with the stationary refiner thereby forming a refining gap therebetween, a feeder for feeding the lignocellulosic fibrous material centrally to a feed zone within the refining gap and a refining zone extending radially outward from the feed zone, the feeding element including a feeder with an upper surface for mounting on the rotary refiner at a location displaced outwardly from and directly adjacent to the central location of the feed zone, the feeder including at least one radial feed bar projecting from the upper surface of the feeder, the at least one radial feed bar including a body and a projecting portion extending laterally from the body at a location displaced from the upper surface of the feeder.
