Ground gypsum has diverse applications in different industries.
In the construction industry, it is mainly used for the production of building gypsum products. Gypsum boards are widely used as interior wall decoration materials, ceiling materials, etc. They have the advantages of light weight, good sound insulation, fire resistance, and easy processing. Gypsum plaster is also a commonly used building material, which can be used for wall plastering and leveling, providing a smooth surface for subsequent decoration.
In the chemical industry, ground gypsum can be used as a raw material for the production of some chemical products. For example, in the production of ammonium sulfate, gypsum reacts with ammonia and carbon dioxide to produce ammonium sulfate, which is an important fertilizer.
In the agricultural field, ground gypsum can be used as a soil conditioner. It can improve the structure of heavy - textured soils, increase soil porosity, and enhance water and air permeability. In addition, gypsum can also provide calcium and sulfur elements for plants, promoting plant growth.
Project Case Analysis
Take a gypsum grinding project in a certain area as an example. The project is an important part of the local building materials industry chain.
Investment Scale: The total investment of the project is several million yuan, including the cost of equipment purchase, plant construction, and installation. The main equipment includes a large - capacity vertical roller mill, a pre - dryer, a crusher, a separator, and a dust collector.
Technical Scheme: The gypsum raw material is first pre - dried to reduce its moisture content. Then, it is fed into the crusher for primary crushing. The crushed gypsum is then lifted to the raw material silo by a bucket elevator. From the silo, it is evenly fed into the vertical roller mill for grinding. After grinding, the powder is separated by the separator. The qualified fine powder is collected by the dust collector and sent to the finished product silo, while the unqualified coarse powder is returned to the vertical roller mill for re - grinding.
Economic Benefits: The project has an annual output value of several million yuan. It not only meets the needs of the local construction and chemical industries for gypsum powder but also brings certain economic benefits to the local area. The project has also created a certain number of jobs, promoting local employment and economic development.
