Abstract

A process is disclosed that is utilized in particular in the preparation of fibrous material of used paper. Hot fibrous pulp friable materials, which are especially suitable for dispersing, are first formed in a compact, high-consistency fibrous material in the form of a plug. In a preferred embodiment, the plug of materials is pushed against a rotor that is equipped with pulverization elements. The pulverization elements remove the fibrous pulp friable materials and distribute them in a disintegrated condition in a processing chamber. In the processing chamber, super-heated vapor is supplied via vapor supply lines, which calefies the fibrous pulp friable materials, for example, by condensation.
