How about red mud using brick making equipment:
Red mud is made of brick-making equipment. Red mud is also called red mud, and it is an industrial solid waste discharged after refining alumina from bauxite. Generally, it contains a large amount of iron oxide, and its appearance is similar to red soil, hence the name. However, some are brown or even off-white because they contain less iron oxide; red mud uses brick-making equipment, and red mud is the polluting waste discharged from the aluminum industry when extracting alumina. 1.0-2.0 tons of red mud.
How about red mud using brick making equipment? As the fourth largest producer of alumina in the world, China discharges millions of tons of red mud every year. Some countries discharge the red mud into the sea, which pollutes the ocean because it contains harmful substances such as alkali, and endangers fishery production. Some are piled up on land, occupying farmland, polluting water systems, blowing with the wind after drying, and polluting the atmosphere.
The red mud uses brick-making equipment, and the red mud is mixed with 20% to make bricks. It can use 750,000 tons of red mud a year and save more than 110 mu of land comprehensively. Using red mud as the main raw material can produce a variety of bricks, such as steam-free fired bricks, fly ash, decorative bricks, ceramic glazed bricks, paving bricks, square bricks, hexagonal bricks, special-shaped bricks, grass planting bricks, slope protection bricks, etc. Red mud uses brick-making equipment, and red mud bricks have greater advantages in water permeability, freeze-thaw resistance, and anti-skid properties than clay bricks; moreover, red mud bricks consume solid waste, and clay bricks are made of ecologically destructive mineral resources. Production. From the comparison of the two bricks, red mud bricks are more energy-saving, environmentally friendly, and resource recycling.
