Gypsum, the main component of which is calcium sulfate, includes natural gypsum and industrial gypsum. The industrial gypsum, also called industrial byproduct gypsum, is a byproduct in some industrial production processes, mainly comprises two types, namely phosphogypsum and desulfurized gypsum, wherein the phosphogypsum accounts for more than half of the industrial byproduct gypsum. At present, the accumulated quantity of industrial by-product gypsum in China exceeds 3 hundred million tons, wherein the phosphogypsum reaches more than 2 hundred million tons. The industrial by-product gypsum is piled up in large quantity, which not only occupies land, but also wastes resources, and the contained acidity and other harmful substances easily cause pollution to the surrounding environment, thus becoming an important factor restricting the sustainable development of phosphate fertilizer enterprises in China. The efficiency of developing and recycling the industrial byproduct gypsum is low at present, and the comprehensive utilization rate is only about 38%; therefore, the development of a secondary utilization technology of industrial by-product gypsum is still a subject of considerable research.

The industrial by-product gypsum product is a gypsum block, a gypsum brick, a gypsum board, a gypsum large wallboard, a plastering gypsum, a gypsum paper and other products which are prepared by taking industrial by-product gypsum as a main material. Because the industrial byproduct waste can be recycled, the industrial byproduct gypsum product has lower production cost, better economic value and great significance in environmental protection, and has wider development and utilization prospect. Particularly, gypsum boards (also called gypsum blocks) and gypsum blocks are widely applied to buildings, and the existing gypsum blocks and blocks are usually produced by adding water into gypsum, stirring the gypsum into slurry, and then casting the slurry, which is called wet production or slurry production. The product produced by the production method needs to be dried after being formed, the process is complex, the energy consumption is high, the energy-saving effect is poor, and the obtained product has low density and poor quality.

In addition, CN200610127778 discloses a method for producing gypsum building products by using extrusion process, in which the gypsum product is produced by adding water to semi-hydrated gypsum and then extruding by means of an extruder, and the process is simpler. However, the following drawbacks still exist in this patent: 1 the process method has complex raw material formula components, and in addition to the gypsum powder, filler powder and various additives are added, so that the process complexity is increased, and the production cost is higher. 2 the process formula is added with the filler powder such as fly ash, fine sand and the like, and the plasticizer is also added as a setting material, if water is added in advance for mixing and stirring, the setting reaction is easy to generate and the process fluidity is influenced, so the process adds the mixing water at the position of an extrusion opening, but the water is difficult to be fully mixed and reacted with the semi-hydrated gypsum to generate the dihydrate gypsum, and the product quality is greatly reduced. 3 the process does not disclose the specific structure of the extruder and the device for conveying and cutting the parts, and has poor practicability.
