The invention provides an apparatus and a method for producing cement, and specifically provides an apparatus and a method for synchronously producing magnesium sulfate cement in a magnesium oxide method flue gas desulfurization process. The apparatus provided by the invention comprises a flue gas desulfurization device, a first concentration device, a discharge device, a second concentration device, a crystallization device, a centrifuge device, a drying device, a waste ash supply device, a slag material supply device, a mixing device, and the like. With the apparatus and the method provided by the invention, problems of large energy consumption and serious environmental damage of current cement productions can be solved. Also, common magnesium sulfate cement problems of high production cost, high material transportation cost, and impossibility of large-scale market popularization can be solved. |
