METHOD OF MAKING PULP

摘要

A method is disclosed of making refiner pulp by refining lignocellulose-containing material having a concentration of 8-15%, measured as discharge concentration. The material is refined in a disc refiner during its passage out through the gap between the refining discs of the refiner to a surrounding refiner housing. Water is continuously supplied to the housing outside the refining discs to dilute the refined material to a fibre suspension of a concentration which is easy to pump. The housing is maintained filled with the suspension in order to reduce the pulp flow through the refiner, and thereby the retention time of the material between the refining discs.
