SYSTEM AND METHOD OF PRODUCING MICRO FIBRILLATED CELLULOSE (MFC)

A system of producing MFC (micro fibrillated cellulose), which system (10) comprises at least one refiner (14, 14A, 14B). The refiner comprises means for refining the stock in at least two refining stages, advantageously at least two refiners (14, 14A, 14B) for refining the stock in at least two ref...

Zusammenfassung:	A system of producing MFC (micro fibrillated cellulose), which system (10) comprises at least one refiner (14, 14A, 14B). The refiner comprises means for refining the stock in at least two refining stages, advantageously at least two refiners (14, 14A, 14B) for refining the stock in at least two refining stages, and that the refiners comprise a number of refining bars. The refining bars have width of 0.5 - 2.0 mm, height less than 7 mm and groove width of 0.5-3 mm. A method of producing MFC, which method comprises at least two refining stages, in which the pulp stock is refined in at least one refining stage (17, 17A, 17B) in consistency of 3 - 5%, and the method comprises at least one screening stage in at least one screen (17, 17A, 17B) in consistency of 0,5-5 %.
