Incineration Bottom Ash Sorting Solutions

Incineration Bottom Ash Sorting Solution: Efficiently Recovering Resources, Turning Waste into Treasure, and Helpingthe SlagCircular Economy

Background

With the accelerating process of urbanization, incineration of domestic waste for power generation has become the mainstream treatment method. However, the bottom ash slag produced after incineration is still rich in a large number of recyclable metal resources, such as iron, copper, aluminum, stainless steel, and even trace precious metals. If directly landfill, not only lead to waste of resources, but also cause environmental pollution.

For this reason, we have launched a one-stop incineration bottom ash sorting solution, through a variety of physical sorting methods, efficient extraction of various types of valuable metals, and make the remaining waste residue into building materials, to truly realize the "waste incineration end of the resource," to help the green cycle of development.

Incineration bottom ash slag sorting process flow

• Pre-processing: The incineration bottom ash is sent into the hopper by forklift, and enters into the drum screen for preliminary screening through the conveyor belt.

• Crushing process: large incineration bottom ash into the crusher, crushing to a uniform particle size, to facilitate subsequent sorting.

• Magnetic separation: the use of permanent magnetic separator to efficiently extract ferrous magnetic metals.

• Jigging separation: Separate heavy minerals by using sawtooth wave jigger, saving water and high efficiency.

• Shaking table sorting: fine sorting of copper, aluminum and non-ferrous metals such as gold and silver.

• Eddy current sorting: precise separation of non-magnetic metals such as aluminum, copper, zinc, etc.

• Dewatering filter press: slag-water mixture through the dewatering screen and filter press to realize slag-water separation and reuse.

• Finished product treatment: tailings are piled up and drained for transportation, and used for brick making or building materials production.
