Process for the preparation of domestic, industrial or similar waste for the extraction of cellulose materials

摘要

The present invention relates to a process for the preparation of domestic, industrial and other similar waste with extraction of cellulose materials, in which the waste material is subjected to a precomminution, magnetic separation, sorting and fractionation. The process is primarily characterised in that the light fraction consisting of paper, textiles and plastics is fed to a washing station and the washed suspended material passed to a pulper, that the ballast materials are removed by means of a filtering after treatment in the pulper and the cellulose particles which pass through the filter and are dispersed in the water are fed as pulp to a possibly adjacent paper mill directly or after the water is pressed out and the pressed-out cellulose particles are dried and recovered as powder.
