Definitions
- the two-stage shredding of the pulp not only enables the shredding performance of the two granulators to be better coordinated, it also prevents damage to the cellulose. It has also been found that a pulp dosage e.g. in a mixer, in which the comminuted pulp is introduced into the aqueous, tertiary amine oxide and the cellulose suspension is produced, is easier and more precisely possible.
