Description

Technical Field

[0001] The utility model relates to the technical field of iron tailings processing, in particular to a device for crushing and dispersing fine-grained iron tailings. Background Art

[0002] Iron tailings are waste products after iron ore dressing. For a long time, the treatment and utilization of iron tailings has been a problem that has troubled mining companies. The accumulation of iron tailings not only occupies a large amount of land, but may also cause environmental pollution and safety hazards. With the development of mineral processing technology, currently 70% to 90% of iron tailings have a particle size of less than 200 mesh. Using iron tailings to prepare unburned ceramsite is an effective way to efficiently utilize iron tailings. As a kind of artificial light aggregate, ceramsite has a wide range of applications in concrete aggregates, water treatment, agricultural soilless cultivation and floor heating backfill.

[0003] In the process of preparing unburned ceramsite, the iron tailings need to be efficiently crushed to disperse them into fine particles or powder. Since the iron tailings are fine and have a high moisture content, generally reaching 30% to 40%, they are easy to form blocks and coarse particles during the drying process, and need to be crushed. Traditional crushing equipment, such as hammer crusher, cone crusher, drum crusher, impact crusher, etc., has low efficiency in tailings dispersion treatment. The tailings are prone to agglomeration, coagulation and adhesion during the crushing process. The tailings need to be crushed and screened multiple times, and the cost of tailings treatment is high, which increases the difficulty of comprehensive utilization of iron tailings. Therefore, the development of efficient equipment for crushing and dispersing fine-particle iron tailings is of great significance for the high value-added utilization of iron tailings.
