Abstract

The refining optimization considering obtaining the desired result in the properties of the refined pulp with the lowest possible energy consumption is discussed in this chapter. Based on the results and discussions of the evaluation of operational variables, the most suitable strategy is proposed, which considers the use of the lowest intensity and highest possible refining consistencies.

The missing variable in models based on refining intensity is identified and described. It is related to the retention time of the pulp in the refiner and is attributed to the flocculation characteristics of the fibers. A new way of designing the discs (configuration) is presented to allow increasing the cutting length of the discs, generating lower refining intensities.
