Refinery and refinery equipment for balancing fibre flows in a refinery

摘要

A refiner segment for a refiner for defibrating has a refining surface comprising a group of first bars and second bars, each having a first end directed in the direction of an inlet zone and a second end directed in the direction of a refining zone, where the second ends of the first bars are interlaced with the first ends of the second bars to form first grooves between the first bars, and second grooves between the second bars. The second ends of the first bars have a guiding surface decreasing from an upper surface of the first bars down towards the bottom of the second grooves, and the first ends of the second bars have a guiding surface increasing from the bottom of the first grooves up to a top of the second bars, such that the guiding surfaces form an equalization groove.
