(1) The production of aluminum salt products uses aluminum hydroxide instead of low-grade aluminum ore raw materials to prevent waste residue and wastewater discharge, and the products are good and the quality is stable.
(2) Production of aluminum salt products using aluminum hydroxide, energy saving and environmental protection. Aluminum sulphate and alum production use aluminum hydroxide as raw material, no external heat source is needed, all use sulfuric acid to dilute heat and reaction heat energy, no sulphur dioxide, carbon dioxide, dust emission, and no production of water vapor during concentrated evaporation, which creates economic benefits for enterprises. It is also very environmentally and socially beneficial.
(3) Polyaluminum production is changed from the original steam heating drum to the hot air spray drying technology to improve the heat utilization efficiency, the product quality is stable and easy to control.
(4) The aluminum sulfate crystal is cooled by water with steel strip, which reduces labor intensity, uniform product particles, shortens the process flow, and has a small footprint.
(5) Adopting international advanced standards, repairing and formulating five new national standards for aluminum salt products, one industry standard, and stricter requirements for indicators, meeting the needs of national economic development and people's living standards, and basically regulating the production of aluminum salt products.
(6) Waste slag as light brick and cement material, comprehensive utilization, and useful exploration, is expected to solve the worries of aluminum salt production.
(7) In the development of new application fields, aluminum sulfate is used as a cement grinding aid and reinforcing agent, and it is used as a coating agent in the compound fertilizer industry; polyaluminium chloride has made great breakthroughs in making sizing agents and flocculants on papermaking.
