Main material characteristics of fly ash brick making machine

Characteristics of main raw and auxiliary materials of fly ash brick making machine

Wet slag: it is the main solid waste discharged from coal-fired power plants. The main oxides of wet slag from thermal power plants in China are SiO2, Al2O3, FeO, Fe2O3, Cao, TiO2, etc. Wet slag is a good raw material for resource utilization as admixture of concrete.

Desulfurized ash: SO2 removal process product, mainly composed of gypsum and reaction lime, impurities, etc., mainly composed of calcium sulfite and calcium sulfate, containing a small amount of fly ash, calcium hydroxide and calcium carbonate.

Calcium carbide slag: waste slag with calcium hydroxide as the main component after calcium carbide hydrolysis to obtain acetylene gas. Acetylene (C2H2) is one of the important raw materials for basic organic synthesis industry. The process of producing acetylene with calcium carbide (CaC2) as raw material and water (wet) is simple and mature. At present, it accounts for a large proportion in China. 1t calcium carbide water can generate more than 300 kg acetylene gas and 10t industrial waste liquid with solid content of about 12%, commonly known as calcium carbide slag slurry. Calcium carbide slag can replace limestone to make cement, produce quicklime, be used as calcium carbide raw material, produce chemical products, produce building materials and environmental treatment.

Tailings ore: solid mineral waste formed by natural dehydration of tailings slurry discharged from concentrator. It is the main component of solid industrial waste and can be regarded as a kind of composite silicate / carbonate and other mineral materials The content of main useful components in tailings is called tailings grade.
