Aluminium dross processing machine

In the realm of aluminum recycling, the Aluminum Dross Processing Machine plays a crucial role in recovering valuable aluminum from aluminum dross.

This byproduct, formed during various melting and refining processes, often contains significant amounts of aluminum trapped within oxides and other impurities.

The dross processing machine tackles this challenge, transforming waste into a valuable resource.

Process aluminium dross effectively to get aluminium metal from aluminium dross

What is aluminium dross?

Aluminum dross is a mass of solid impurities floating on molten metal.

As aluminum metal melting point is 660℃, which is low-melting-point, so it will be formed on the surface in aluminum melting or alloys by oxidation of the aluminum.

Approximately “millions of tons of aluminum dross is produced per year in the world.”

There are two primary types of aluminum dross: black and white.

Black dross, also known as dry dross, has a granular texture.

It tends to have a low metal content and a high concentration of salts and oxides.

White dross, which is wet, has high concentrations of metal and a smaller amount of salts and oxides.

Aluminum dross generating causes

The reason why aluminum dross is produced in such high quantities in the world is that aluminum is a material commonly utilized in the production of a number of products including “pistons, engine and body parts for cars, beverage cans, doors, siding and aluminum foil.

Aluminum dross is a byproduct formed during the melting and processing of aluminum.

It’s a complex mixture of solid components, largely comprising aluminum oxides, metallic aluminum particles, and other impurities like salts, nitrides, and carbides.

Here’s a breakdown of the main causes of aluminum dross generation:

Oxidation:

When molten aluminum comes into contact with air, it readily reacts with oxygen, forming aluminum oxide (Al₂O₃). 

This oxide forms a dross layer on the surface of the melt.

Factors that promote oxidation include:

High melting temperature: Increased temperature exposes molten aluminum to air for a longer duration, boosting oxidation.

Turbulent mixing: Agitation and splashing during melting can increase surface area exposed to air, leading to more dross formation.

Moisture and contaminants: The presence of moisture in scrap or furnace atmosphere, along with oil, paint, and other contaminants on scrap, can accelerate oxidation and dross formation.

Incomplete melting:

If scrap aluminum isn’t fully melted during the process, residual metallic aluminum can get trapped within the dross, impacting recovery and increasing waste.

Factors contributing to incomplete melting include:

Improper charging: Uneven or slow charging of scrap can cause uneven heating and incomplete melting.

Incorrect temperature control: Insufficient temperature may not melt all the scrap, leaving behind aluminum particles in the dross.

Furnace inefficiencies: Issues with furnace design, burner performance, or insulation can lead to uneven heat distribution and incomplete melting.

Chemical reactions:

Some impurities in scrap, like magnesium or zinc, can react with aluminum and form intermetallic compounds that contribute to dross formation.

Fluxing agents used to remove impurities can also react with the molten bath and generate additional dross, although their overall role is to minimize dross formation due to other contaminants.

Understanding these causes is crucial for minimizing aluminum dross generation and improving the efficiency of your melting and processing operations.

By implementing control measures like controlling temperature, minimizing air exposure, optimizing mixing, and using appropriate fluxing agents, you can significantly reduce dross formation and reclaim valuable aluminum for further use.

Aluminium dross processing current situation

In the current overview of systems and technologies for the treatment of aluminum dross removed from aluminum melting furnace and holding furnaces, aluminum dross recovery machine is by far the most widespread technology which ensures the best economic results, as well as environmental and operational benefits.

There will be lots of aluminum dross in the melting process, which (residue) contains a large amount of aluminum with the residue removal from the furnace.

If we sell them with simple processing, that will cause great waste and also it pollutes the environment.

But if we use a rotary furnace, grinding separation by cold ash, pressing and labor dross processing and these methods are not only a low recovery rate, but also a big waste and harmful to the environment.

So it is particularly important to maximize the recovery of aluminum from aluminum dross.
