ABSTRACT:
A process of preparing a suspension of paper making fibers in water for use in the making of paper includes the steps of treating a mass of fibrous materials, such as shredded waste paper materials, with steam under pressure in a closed vessel, and transferring the resulting mixture of treated materials and steam to a second vessel containing a substantial volume of aqueous liquid in such manner that the mixture impacts directly the liquid in the second vessel at very high velocity causing disintegration of the solid materials into essentially separate fibers and contaminant particles accompanied by dispersion of these solids in the liquid in the second vessel. Systems are described for carrying out these process steps on either a continuous or a batch basis.
