Aluminium dross rotary furnace
Aluminium dross rotary furnace is one kind of necessary tool in the aluminum dross processing of recycled aluminum industry, which is one important part that reflects operation cost and profile of recycled aluminum recycling.
Our machine is specialized in processing hot dross skimmed from the melting furnace.
Through rotating and stirring, adding chemical agents and setting, then we can get pure aluminum liquid for aluminum ingot.
The rotary furnace is suitable for mass processing of hot dross, cold dross and aluminum dross containing big iron scraps.
The staffing is small, and only one skilled forklift operator and one auxiliary worker are needed.
It can process several tons to dozens of tons of hot and cold aluminum dross a day, and the work efficiency is extremely high.
The hot aluminum dross skimmed out from the furnace is sent into the rotary furnace with a rotary forklift, and the aluminum liquid in the aluminum dross can be separated by using the reverse rotation of the rotary furnace and the back and forth stirring of the forklift rake.
During the operation, attention should be paid to controlling the temperature, can add cold dross or small pieces of cast aluminum as a temperature control agent and secondary refining.
After the treatment is completed, tilt the body of the rotary furnace with a hydraulic oil cylinder to pour out the aluminum liquid.
After the aluminum liquid is poured, rotate the body of the rotary furnace to unload the dross.
The operation is simple and convenient.
The recovery rate of rotary furnace can reach more than 80%.
If it can work together with the dross cooling and sieving machine, the comprehensive recovery rate can reach more than 90%.
Rotary furnace and dross cooling and sieving machine are ideal equipment to process aluminum dross and cold dross in large quantities.
Due to the centralized treatment, the generated dust and smoke generated in the dross processing with the rotary furnace is convenient for centralized collection, which truly achieves energy saving and environmental protection.
An Aluminum Dross Rotary Furnace is a powerful tool in the realm of aluminum recycling.
It tackles the challenge of processing dross, a by-product generated during various aluminum melting processes.
This furnace not only recovers valuable aluminum from the dross but also plays a crucial role in optimizing resource utilization within the industry.
Function:
Dross Feeding: The furnace receives dross, typically in the form of chunks or briquettes, through a charging port.
Melting and Separation: As the furnace rotates, the dross is exposed to high temperatures, causing the aluminum (having a lower melting point) to separate from the impurities and slag.
Metal Tapping: Molten aluminum is periodically tapped and collected from the furnace.
Slag Discharge: The remaining slag and impurities are periodically removed from the furnace through dedicated outlets.
Key Features:
Rotating hearth: The heart of the furnace is a cylindrical hearth that rotates continuously, ensuring uniform exposure of the dross to heat and facilitating efficient melting and separation.
Controlled heating system: Precise temperature control allows for optimal melting and efficient separation of aluminum from impurities.
Slag removal mechanisms: Dedicated channels or tilting mechanisms efficiently remove slag and prevent contamination of the molten aluminum.
Dust extraction system (optional): Some models come equipped with a system to control dust and fumes generated during the process, improving air quality and operator safety.
Control panel: The entire process is monitored and controlled through a user-friendly interface for optimal performance and safety.
Advantages:
High aluminum recovery: Efficiently recovers valuable aluminum from dross, minimizing waste and maximizing resource utilization.
Reduced energy consumption: Optimized design and continuous rotation ensure efficient heat distribution and reduce overall energy consumption.
Improved metal quality: A controlled melting process minimizes contamination and produces high-quality molten aluminum suitable for remelting into new products.
Reduced environmental impact: Lower energy consumption and efficient dross processing contribute to a more sustainable aluminum recycling industry.
Cost-effectiveness: High aluminum recovery rates and efficient operation translate to lower costs per unit of recovered aluminum.
Applications:
Secondary aluminum production: Processing dross generated from recycled aluminum sources.
Primary aluminum smelters: Treating dross generated during initial aluminum production stages.
Foundries: Recovering aluminum from foundry dross for remelting and incorporation into new castings.
Overall, the Aluminum Dross Rotary Furnace plays a vital role in the aluminum recycling industry.
Its ability to efficiently recover valuable aluminum, minimize waste, and improve operational efficiency makes it critical equipment for any facility seeking to close the loop and contribute to a more sustainable aluminum production cycle.
The process of aluminium rotary furnace
The process of aluminum dross in the rotary furnace is inside heating, it means that we use the heat coming from aluminum dross self-ignition (during the high-temperature period of self-ignition, waiting for the heating between the stirring of high-temperature aluminum dross and ash), so that can improve the melting speed of aluminum and aluminum liquid temperature, reduce aluminum viscosity, easy for the separating aluminum liquid and aluminum ash.
Aluminium dross rotary furnace can reduce aluminum content in the aluminum dross from 40-60% to 15-17%, high aluminum recovery rate (about 80%).
The dust generated in the production process gets controlled, not only reduce the working strength, but also improve the dross processing environmental pollution.
Technical data of aluminium rotary furnace
Rotary furnace dross capacity and rotating speed 4.5 tons-5 tons aluminum dross can be done for 5 tons rotary furnace each time (in of them, hot aluminum dross is about 3.5T- 4 T, the rest is cold dross)
Rotating speed: 1.5-2 R/Min
Processing time of rotary furnace
It will take 2- 4 hours to finish the processing. The time will be different from the proportion of cold dross and hot dross.
Rotary furnace recovery rate ≥80﹪( the aluminum content in the hot aluminum dross is about 40-60%)
