Aluminum Can Recycling Decoating and Melting Solution for Clean Aluminum Recovery

Every used beverage can represents far more than discarded packaging—it is a valuable aluminum resource waiting to be recovered. As demand for low-carbon aluminum continues to rise, recycling companies, secondary aluminum smelters, metal processors, and circular economy investors are looking for more efficient ways to convert used beverage cans (UBCs) into high-value recycled aluminum. Yushunxin designs the aluminum can recycling decoating and melting solution for recycling plants that want cleaner aluminum feedstock, lower melting pressure and higher-value recycled aluminum products.

What Projects and Materials Are Suitable for This Aluminum Can Recycling Solution?

How Does the Aluminum Can Recycling Process Work?

The process usually starts with bale opening and shredding. If your cans are compressed into bales, direct heating is inefficient because the heat cannot pass through the material evenly. Yushunxin usually suggests shredding the cans into smaller pieces, commonly around 2–5 cm depending on the project design. This gives the material better looseness, improves heat transfer and supports more stable decoating.

After shredding, magnetic separation can remove iron impurities, while non-ferrous sorting can help improve aluminum purity before the thermal stage. This step is important if your raw material comes from mixed scrap yards. A cleaner material flow reduces unnecessary furnace load and protects the quality of the final aluminum product.

The shredded aluminum cans enter the aluminum can decoating furnace for low-oxygen thermal treatment. In many projects, the furnace temperature is controlled around 420–500°C. For materials with different coating thickness, moisture or impurity levels, the working window can be adjusted within about 400–600°C. This temperature range allows paint, ink, lacquer and organic coating to crack, volatilize or carbonize, while the aluminum base remains solid because aluminum melts at around 660°C.
For shredded aluminum cans, the residence time inside the decoating furnace is commonly around 30–50 minutes. If your material is thicker, dirtier or less uniform, Yushunxin can adjust the feeding speed, furnace length, heating zone and air control. The goal is simple: clean enough aluminum surface before the melting stage.

After thermal decoating, paint residues become light carbon dust or fine ash. A drum cleaning or dust separation system removes these residues from the aluminum surface. This step helps reduce floating ash, smoke and impurity load when the material enters the aluminum melting furnace.

After decoating and dust separation, the clean aluminum pieces enter the aluminum melting furnace. If your target is aluminum ingot casting, the melting temperature can be controlled around 720°C. If your downstream process needs molten aluminum for direct use, the temperature can be raised to around 760°C. This flexible temperature control helps you choose the product route according to your market, buyer requirement and plant layout.

What Final Products Can You Get from the Line?

Why Does the Combined System Bring Better Project Value?

When you use a decoating furnace and melting furnace as one coordinated line, the energy flow becomes more efficient. The combustible gas generated during decoating can be collected and sent to the combustion system as supplementary heat. This reduces dependence on external fuel and supports a lower operating cost.
Clean aluminum also melts more smoothly. Since most organic coatings have already been removed, the melting furnace faces less smoke, less odor, less slag and less unnecessary heat loss. For your daily operation, this means fewer interruptions, easier furnace management and better control over product quality.

If your plant is facing stricter environmental inspection, direct melting of painted cans can create a high burden for the smoke treatment system. Yushunxin’s Aluminum Can Recycling Decoating and Melting Solution works in a sealed low-oxygen environment, and the exhaust can pass through dust removal, secondary combustion and tail gas treatment before discharge. The process does not require acid or alkali washing, so there is no chemical stripping wastewater.

For many recycling businesses, environmental cost is part of the real production cost. By treating coatings before melting, you can reduce smoke control pressure at the source and make the whole project easier to operate under local emission requirements.

If you have stable can supply, a continuous decoating and melting route can support long-hour operation. Yushunxin can configure continuous feeding, automatic temperature control, material conveying, carbon dust separation, melting, tail gas treatment and optional ingot casting equipment. This reduces manual handling and helps you plan daily capacity more accurately.
A smoother process is especially useful when your business grows from simple scrap collection to industrial recycling. You need stable output, predictable labor demand and controlled energy use. A properly designed line can help you reach those targets.

A clean aluminum surface improves melting quality and makes product upgrading easier. After melting and refining, your output can be used for aluminum ingots, alloy ingots, aluminum casting, rolling materials or can-grade recycling projects. If your buyers care about cleaner recycled aluminum, this pretreatment route gives you a stronger selling point.

If you have stable UBC supply, face smoke or slag problems during direct melting, or want to upgrade from scrap selling to aluminum ingot or molten aluminum production, Yushunxin can help you configure a suitable Aluminum Can Recycling Decoating and Melting Solution. According to your material condition, daily capacity, fuel type, plant layout and final product target, the line can be designed as a decoating pretreatment system, a complete decoating and melting line, or a turnkey solution with refining and ingot casting.
