PROCEDURE FOR CONTROLLING THE PULP QUALITY FROM REFINERS

By refining/grinding of pulp there is a need for using measurement information from traditional process variables in combination with measurement signals from the refining zones of refiners for estimating the quality of pulp output from refiner lines. The present invention enables this and relates t...

Zusammenfassung:	By refining/grinding of pulp there is a need for using measurement information from traditional process variables in combination with measurement signals from the refining zones of refiners for estimating the quality of pulp output from refiner lines. The present invention enables this and relates to a method for improving the control of the refining process in one or several connected refiners by using estimated pulp quality information from each refiner in order to quickly be able to control the refining at disturbances to the process.
