Hereinafter from the raw material and from the weighting materiel partly being present in the raw materiel in a quantity of et least 7 weight-%, advantageously 10 weight-%, in a grain size of 0-0,5 mm, pertly recycled from the process, e mixture of sludge is prepared in the presence of a liquid phase, while the density of the sludge mixture is adjusted in accordance with the extent of separation. The sludge mixture is allowed to pass through one or more hydrocyclones and equipments separating according to grainsize end/or grading equipments, The density of a part or of the entirety of the streaming suspension is adjusted in accordance with the required density of the sludge mixture, and the suspension in a density thus adjusted is recycled to the sludge production, The product resulting from separation and the suspension not having been recycled are discharged from the system. In case of necessity the process is partly or entirely automatically controlled.
