Disintegration and refining of pulp

The disintegration and refining of pulp are two essential, high-energy consumption processes upstream of the fabrication of chain of papers and cardboards. Disintegration transforms the pulp into an aqueous, fibrous and homogeneous suspension. Refining then subjects this suspension to a mechanical processing that brings physical, chemical and morphological modifications to fibers. The equipment used varies according to the nature of the fibrous raw material, which can be in the form of pulp bales, mass fraction suspension or recovered cellulose fibers. The aim of disintegration is to obtain an homogeneous, pumpable fibrous suspension as well as the separation of coarse contaminants from fibers.
