Abstract

Die Erfindung betrifft ein Verfahren zur Mahlung von Faserstoffen zwischen zwei Mahloberflächen. Es ist vornehmlich dadurch gekennzeichnet, dass die Differenzgeschwindigkeit der Mahloberflächen im Bereich von -5 m/s und +12 m/s liegt, wobei die Differenzgeschwindigkeit vorteilhafterweise nahezu Null ist. Die Erfindung betrifft auch eine Vorrichtung zur Durchführung des Verfahrens. Bei dieser sind erfindungsgemäß als Mahlkörper Walzen 2,3,2',3',10,11,12 vorgesehen.The invention relates to a method for grinding fibrous materials between two grinding surfaces. It is mainly characterized by that the difference in speed of the grinding surfaces in the Range of -5 m / s and +12 m / s, the difference in speed is advantageously almost zero. The invention also relates to a Device for performing the method. With this are According to the invention, grinding media 2, 3, 2 ', 3', 10, 11, 12 are provided.
