METHOD FOR CONTROLLING QUALITY OF PULP

摘要

The invention relates to a method for controlling the quality of pulp. Pulp produced by mechanical defibering of wood is screened to provide at least tw o fractions, of which the accept that has passed the screening phase is carrie d forward for use and the reject that has not passed the screening is removed from the screening phase (3; 5; 8). An underlying idea of the invention is that the consistency (C2; C3; C5) of the reject that is to be removed from t he screening is measured and the consistency value thus obtained is used for controlling the defibrator (1; 7) to adjust the quality of the accept.
