The completed system and total solution for hot aluminium dross recycling.
An aluminium dross processing system is a specialized setup designed to recover valuable aluminium metal from the dross generated during the melting and casting processes in the aluminium industry.
Dross is a mixture of metallic aluminium and non-metallic impurities like oxides and salts, forming a solid mass that floats on the surface of molten aluminium.
Recovering this metal from dross is crucial for environmental sustainability, resource efficiency, and cost savings.
Here’s a breakdown of the main machines involved in an aluminium dross processing system and their functions:
Dross processing machine (DPM), also known as aluminium dross machine and aluminium dross separator, it is the base of the aluminium dross processing system.
Function: Mechanically stirring and processing hot dross to maximize metal separation. It can extract more than 90% aluminium from hot aluminium dross.
Dross cooling machine can cool the hot dross to normal temperature in a short time.
Function: Rapid cooling is essential for further processing and handling. Typically, a circulating water cooling system is used to effectively cool the dross, making it easier to handle and process further.
Ball mill and sieving machine
Function: The ball mill is responsible for crushing and grinding the cooled dross into smaller particles.
This increases the surface area of the dross, making it easier to separate the aluminum from the impurities during the next stage.
Process: The ball mill is a cylindrical chamber filled with steel balls of varying sizes. As the chamber rotates, the balls tumble and crush the dross against the inner lining and against each other.
The size of the balls and the speed of rotation can be adjusted to achieve the desired particle size.
Dross sieving machine
Function: After the dross is ground in the ball mill, it is passed through a series of vibrating screens to separate it into different size fractions.
The screens have mesh sizes that allow particles of different sizes to pass through.
Separation: Typically, there are three or four screens with varying mesh sizes.
The largest screen allows the largest aluminum particles to pass through, while the smallest screen allows only the finest powder to pass through.
The intermediate screens capture particles of different sizes in between.
Benefits: Separating the dross into different sizes facilitates further processing and utilization.
Larger particles can be directly remelted, while smaller particles may be used for other applications such as casting alloys or in the construction industry.
the aluminum dross ball mill and screening machine work together to efficiently process aluminum dross and recover valuable metal.
By crushing and grinding the dross, and then separating it into different sizes, the system maximizes the recovery of aluminum while minimizing waste.
Benefits of Aluminium Dross Processing Systems:
Increased aluminium recovery: Advanced systems can achieve up to 90% aluminium recovery from dross, significantly reducing waste and maximizing resource utilization.
Reduced environmental impact: By recovering aluminium from dross, the need for virgin aluminium production decreases, leading to lower energy consumption and greenhouse gas emissions.
Improved operational efficiency: Automated systems minimize manual labor and downtime, leading to increased production efficiency and cost savings.
Enhanced product quality: Recovered aluminium from dross can be used in various applications, often with minimal impact on product quality.
Overall, aluminium dross processing systems are a valuable investment for the aluminium industry.
They offer a sustainable and efficient way to recover valuable metals from waste, reduce environmental impact, and improve operational efficiency.

One completed cycle for aluminium dross recycling.
Function:
The system primarily accomplishes two main functions:
Aluminum Separation: This involves extracting the valuable aluminum metal from the dross mixture, which typically contains aluminum, oxides, salts, and other impurities. This is achieved through various specialized equipment within the system.
Dross Processing and Utilization: The remaining non-aluminum dross is processed and prepared for further use or disposal. This may involve crushing, sieving, and/or other treatment methods depending on the intended application.
Key Features:
High-speed Aluminum Dross Processor: This machine is the heart of the system, utilizing mechanical force and sometimes chemical techniques to efficiently separate the aluminum metal from the molten dross. Advanced designs can achieve recovery rates exceeding 90%.
Dross Cooling machine: after the extraction of aluminum from the hot dross, utilize a rapid cooling system to solidify the dross for easier handling and storage, avoid the burning loss and increase the aluminum recovery rate.
Aluminum Dross Ball Mill and Sieving System: Ball mill for dross crushing and grinding, screens categorize the cooled and crushed dross into different sizes based on the remaining aluminum content and particle size. This allows for targeted reuse or disposal of the dross fractions.
Integrated Control System: The entire system is controlled and monitored by a central system for safe and efficient operation, optimizing performance and minimizing processing errors.
