Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a gypsum and mineral powder feeding and regulating device. Background Art

[0002] Gypsum and mineral powder are added to cement production to improve cement performance and quality and reduce environmental pollution. Gypsum is a mineral, and adding an appropriate amount of it to cement production can control the cement's hardening rate. This is because the gypsum in gypsum reacts with the calcium sulfate in cement to form a relatively stable hardening product, which slows the setting and hardening of the cement, resulting in better processing properties and facilitating construction operations. Using mineral powder as a cement admixture fully utilizes mineral resources, reduces resource waste, and lowers production costs. The addition of gypsum and mineral powder improves cement's physical properties, such as increasing its compressive strength, impermeability, and durability, thereby enhancing its engineering quality and service life. In cement production, the addition of gypsum and mineral powder reduces coal consumption and carbon dioxide emissions during clinker firing, minimizing adverse environmental impacts and meeting the requirements of sustainable development. Currently, gypsum and mineral powder are added manually by weighing them separately. Manual weighing cannot precisely control the ratio of gypsum to mineral powder, which in turn affects the quality of the produced cement. Utility Model Content
