The invention relates to a process for crushing a cellulose material in which crushing takes place in at least two stages, where (1) the cellulose material is precrushed, whereby particles of various sizes are formed, (2) the particles produced in the pre-crushing process are conveyed, without the separation of any particle sizes, to a device in which the size of the particles is further reduced.
L'invention concerne un procédé de désintégration d'un matériau cellulosique, caractérisé en ce que la désintégration se fait en au moins deux phases, à savoir, (1) en effectuant un prébroyage du matériau cellulosique, ce qui conduit à la formation de particules correspondant à des fractions de grosseurs différentes, (2) en transportant les particules formées lors du prébroyage, sans séparation d'une fraction quelconque de particules de grosseurs différentes, vers un dispositif où ces particules continuent d'être désintégrées.
