Landfill: Directly buried underground. This method does little harm to human body, but it has a great influence on crop planting when buried in the ground, because the pollutants contained in aluminum ash will reduce the fertility of soil, reduce the nutrients needed for plant growth, and more seriously, make crops grow some mutated things, which will affect the overall yield.

Aluminum ash separator: the aluminum ash separator can treat aluminum ash without pollution, and the aluminum ash actually contains aluminum 1%~ 12%. The aluminum ash separator can be used for secondary processing to extract the aluminum content in aluminum ash. The researchers also made use of the residue left by the secondary processing of aluminum ash, which can be used as electrolytic aluminum rods or chemical additives.

Users should pay attention when dealing with aluminum slag.

Because the aluminum ash treatment method is a dry system, it produces a lot of dust. Therefore, the whole system needs to be sealed with dust cover and cyclone to ensure the normal working environment. It can also be connected with hot ash treatment to improve efficiency.

The treated aluminum particles can be directly used for smelting. Aluminum ash can be used as raw material to produce aluminum chloride series water purification agents, so that waste aluminum can be recycled and used to the best of its ability. Or use the treated aluminum ash as binder instead of cryolite as raw material for electrolytic aluminum. Throughput varies depending on the configured machine.
