Abstract
An apparatus and method for defibering paper and dry pulp in a substantially dry processing environment is disclosed. The apparatus and method for defibering paper and dry pulp uses a dry processing cell into which cellulose material is supplied. The dry processing cell includes a rotating element for creating a turbulent air flow within the cell. The turbulent air flow causes the cellulose material to be circulated within the dry processing cell and to collide with the rotating element, cell walls, and the cellulose matter, itself. This circulation causes disassociation of the cellulose material from the filler, inks and other materials into single cellulose fibers that are capable of being removed from the cell for further processing.
