Verfahren und Einrichtung zur kontinuierlichen Herstellung von Formkoerpern aus anorganisch gebundenen Werkstoffen.
A process and a device for the continuous production of moulded elements made of anorganically bound materials are presented. A strand of material is compacted in a high-pressure compaction unit in such a way that its thickness drops below the nominal thickness of the finished material strand and its density exceeds its nominal density. In the following calibration device, no active pressure is applied. It is important here that the material strand passes through a depressurized zone (5) after leaving the high-pressure compaction unit (2) and that then, directly prior to entry into the calibration unit (4), it is so highly compacted that the resilience produced while passing through the depressurized zone (5) is either completely neutralized and the density of the material strand exceeds the nominal density of the finished material strand and the thickness of the said strand is not attained when it is fed into the calibration unit (4) or the resilience is only neutralized to the extent that the thickness of the material strand corresponds to the nominal thickness, and the density of the material strand corresponds to the nominal density of the finished material strand.
