<p>The invention relates to an installation or plant for making sintered brick blanks, which includes a material preparation plant, a press and molding device, a drying and sintering device, a discharge device and feeding means, as well as a central power source, and control and monitoring devices. The material consisting, for example, of clay, loam, clay marl with aluminum oxide and liquid medium, is prepared in the material preparation device and is formed into a strand by means of an extruder in the form molding device. The strand is then cut into brick blanks by means of a strand cutter and a wire cutter. The brick blanks are transferred with suitable transfer means and a displacement device in a defined, spaced-apart relationship, onto a transfer truck and from there onto a drying and sintering truck. A plurality of drying and sintering trucks run in a closed series through a tunnel dryer at an optimum speed for the drying process. After the discharge of the trucks from the tunnel dryer, the trucks with the pre-dried brick blanks are moved back in accordance with a counterflow principle, through a sintering furnace, which is above the tunnel dryer. After the sintered brick blanks are discharged from the sintering furnace, they are fed to the discharge means by another transfer truck, and are then removed in groups from the truck, whereby the truck is moved back to the loading station by means of an elevator.</p> |
