Our company committed to becoming continuous leader in “melting and casting” equipment.Our company’s main products include melting furnace series,casting equipment series,aluminum dross treatment series,environment protection dust collector series,scrap metal sorting system series……From casting to terminal,serving thousands of industries.
Aluminum dross recycling production line is an industrial system that integrates mechanical, thermal, and environmental protection technologies.It is designed to efficiently recover residual metallic aluminum from the waste dross (also known as aluminum ash) generated during aluminum melting and casting processes,and to further treat the final residues for harmless disposal and resource utilisation.
This production line is not only an effective means of improving resource efficiency, but also a critical step for modern aluminum processing enterprises to meet environmental compliance requirements and enhance economic benefits.
Product Introduction
The hot dross after refining aluminum water in the aluminum dross separator or rotary furnace can cool 700-900°C high-temperature aluminum dross to normal temperature within 10-15 minutes through water spray heat exchange,avoiding the high temperature aluminum dross Burning,oxidation,and grading screening can basically realize mechanized operation,while automatically separating coarse and fine dross(40-80 mesh).
Core Process Flow of The Aluminum Dross Recycling Production Line in Juchen Equipment
A complete aluminum dross recycling production line typically includes the following core stages:
Hot-state recovery (aluminum extraction)
– This is the stage that generates the greatest economic value. Hot dross (about 700–900 °C), freshly skimmed from the melting furnace, is fed into equipment such as a rotary furnace.
– Through rotation and stirring of the furnace body, and with the addition of a fluxing agent to modify the interface between aluminum and dross, the molten aluminum is collected and separated.
– The recovered molten aluminum can be directly cast into ingots or transferred to holding furnaces for further production. The aluminum recovery rate at this stage can reach over 70 %, and with advanced processes it can even exceed 95 %.
Cooling and stabilisation
– After the liquid aluminum is separated, the remaining hot ash (primary aluminum dross) must be rapidly cooled.
– A dross cooling barrel/cooler is the core equipment here. Through indirect water cooling via water spray on the outer shell, the dross is quickly cooled to below 50–60 °C while being tumbled, effectively preventing further oxidation of aluminum and solidifying hazardous substances.
Crushing and screening (resource recovery)
– The cooled dross is sent to a ball mill for crushing, and then classified by particle size through a screening machine.
Typically, products such as large lumps, medium lumps, and fine ash are separated.
Large/medium lumps contain a higher proportion of aluminum and can be returned to the furnace for re‑melting.
Fine ash (secondary aluminum dross)
– This is a finer material that, depending on its composition, can be used to produce refining slag, calcium aluminate powder, refractories, or as a raw material for cement and other building materials.
Technical Features and Trends
High recovery efficiency
– Modern production lines can achieve aluminum recovery rates of 80 % – 90 % or even higher.
Highly automated
– From feeding to discharging,the entire process can be controlled automatically, reducing manual labour and increasing efficiency.
Environmental compliance
– Integrated dust collection and exhaust gas treatment systems are key to achieving cleaner production.
Resource utilisation
– The final product (secondary aluminum dross) is no longer waste;it can be used as a raw material in building materials,chemicals,and other fields,aligning with the principles of the circular economy.
Our company product also can install the CMS system on different devices.The CMS is an industrial interconnection PaaS platform that provides customers with overall olutions for intelligent equipment systems and assists in the digital transformation and upgrading of users in the non-ferrous metal industry.It is very convenient to use.The CMS system can provide web publishing and mobile apps that can be accessed anytime and anywhere through computers,tablets,and mobile phones.And it can integrate custom multilingual tools,allowing for the free addition of new languages,making it easy to switch between multiple languages.
The aluminum dross recycling production line is an integrated system combining resource recovery and environmental disposal.Through physical and thermal processes,it transforms industrial waste dross into reusable resources and raw materials.
