Description

Iron tailings slag crushing and mixing device for shotcrete Technical Field

[0001] The invention relates to the technical field of shotcrete, in particular to an iron tailings slag crushing and mixing device for shotcrete. Background Art

[0002] Shotcrete is concrete constructed using the spraying method. There are two construction methods for shotcrete: dry mix and wet mix. The dry mix method is generally used. Cement, sand, and gravel with a maximum particle size of less than 25 mm are mixed in a specific proportion. The mixture is then loaded into a sprayer. Compressed air is used to transport the dry mix along a pipeline to the nozzle, where it is mixed with water and sprayed onto the work surface at a high speed of 40 to 60 meters per second. The wet mix method involves pre-mixing the raw materials with water before spraying. During shotcrete construction, the collision and continuous compression of cement particles and aggregate, combined with a low water-cement ratio, results in a dense, high-strength, and durable concrete.

[0003] Tailings sand is the waste product discharged by mineral processing plants after grinding ore and extracting its useful components under specific economic and technical conditions. It is a solid mineral waste formed by the natural dehydration of tailings slurry discharged from mineral processing plants. The main component of solid industrial waste can be considered a composite of mineral materials such as silicates and carbonates. The content of the main useful components in the tailings is called the tailings grade. It is a solid mineral waste formed by the natural dehydration of tailings slurry discharged from mineral processing plants.
