Method for refining aqueous suspended cellulose fibers and refiner fillings for carrying out said method

摘要

A method for refining aqueous suspended cellulose fibers including the step of guiding the fibers in an aqueous suspension between refiner fillings. The refiner fillings are provided with refining strips and interposed grooves and are located either on a rotor or a stator. The refiner fillings are caused to be rotatably moved relative to each other and pressed against each other, thereby transmitting mechanical a refining action to the cellulose fibers. The refiner fillings include barriers in at least part of the grooves, the barriers closing the grooves at least partially.

1. A method of refining an aqueous suspension of cellulose fibers, the method comprising the steps of:
guiding the fibers in the aqueous suspension between a plurality of refiner fillings located on at least one of a rotor and a stator, said refiner fillings including a plurality of refining strips and a plurality of interposed grooves, at least a portion of said refiner fillings including a plurality of barriers in at least a portion of said grooves, said barriers at least partially closing said portion of said grooves and a depth of said grooves one of increasing and decreasing toward an outside of said at least one of said rotor and said stator; causing said refiner fillings to be moved rotating relative to one another and pressed against one another to transmit a mechanical refining action to the cellulose fibers.
