Technical Field

[0001] The invention belongs to the technical field of mixing devices, and in particular relates to a mixing device for preparing building materials based on tailings. Background Art

[0002] Tailings are waste products left after mineral processing and are a major component of industrial solid waste. With the rapid development of the metal industry, especially the steel industry, the amount of tailings is increasing rapidly. The large accumulation of iron tailings not only greatly wastes limited land resources and increases the cost pressure of maintaining tailings ponds, but also causes environmental pollution and harms the local ecological environment. The use of tailings to prepare green building materials (such as concrete aggregates, permeable bricks, and unfired expanded clay) is regarded as a key path to "turning waste into treasure." However, due to the complex physical and chemical properties of tailings (such as uneven particle grading, large fluctuations in water content, and high levels of sulfur / metal impurities), traditional concrete mixing equipment or powder mixing devices face multiple challenges in their application.
