Abstract
The method of dispersing a material containing waste paper by means of a dispersion apparatus and a dewatering machine, renders possible performing the material dispersion operation at essentially constant specific dispersion work even when encountering fluctuations of the raw material to be dispersed and of the dispersing process itself. For this purpose there is provided a regulating system which, with the aid of measured values or magnitudes derived from the dispersing process and predeterminate processing relationships, controls the addition of diluting water to the material to be dispersed at a location upstream of the dispersion apparatus.
