Abstract:
A method for production of a gypsum fiberboard panel, has the following method steps: production of a mixture of calcined gypsum and fibers; application of the mixture to a gas-permeable and/or air-permeable and/or liquid-permeable conveyor that continuously moves in an advancing direction, at an advancing speed; pre-compaction of the mixture; wetting of the mixture with setting water; post-compaction of the mixture; pressing the mixture to form a gypsum fiberboard panel strand; cutting the gypsum fiberboard panel strand into individual gypsum fiberboard panels; drying the gypsum fiberboard panels; and if necessary, finishing and/or coating the dried gypsum fiberboard panels; wherein for pre-compaction, the mixture is sprayed with a water mist and has a partial vacuum applied to it. Furthermore, an apparatus produces a gypsum fiberboard panel, in particular by carrying out the method, and a gypsum fiberboard panel is produced using the method and/or using the apparatus.
