Background

When the waste building is dismantled, a large amount of waste cement concrete and calcifications are generated, such as putty on inner and outer walls, namely calcium carbonate, and the ecological environment is gradually deteriorated due to the building waste materials; in addition, in order to produce new cement, a large amount of limestone ore must be mined from the nature, and the ecological natural resources are also destroyed. The resources of natural limestone mine are very limited and are increasingly scarce. Meanwhile, the main component of limestone ore is calcium carbonate (CaCO3), and in the process of producing industrial products such as cement, glass and the like by using natural limestone ore, the limestone ore is calcined at high temperature to generate quicklime (CaO).

In the prior art, the construction waste is usually screened, and stones, concrete blocks and broken bricks in the construction waste can be directly used for reinforcing foundation foundations, or the construction waste is used for manufacturing landscape engineering; or crushing the construction waste to obtain particles of the construction waste, and directly recycling the particles. For example, the particles are used as recycled aggregates in mortar and concrete, or used for foundation of building engineering and road surface cushion, or used for preparing green concrete, or used as particle adsorbents for reducing the concentration of phosphorus in water after crushing cement bricks, or used as defluorination adsorbents prepared by using waste cement paste as a raw material, and the like. This method of utilizing construction waste produces a lot of powder and fine particles when granulating the construction waste, and the fine particles are mixed with a lot of sand and stone which are not capable of converting calcium carbonate and thus cannot separate calcium carbonate for reuse. For this purpose, we propose a device for classifying and converting construction waste into calcium carbonate.
