Auxiliary Equipment for
Aluminium Recycling Plants

The machine operates autonomously, eliminating the need for an operator. This ensures the safety of the operators by keeping them away from the danger area in front of the furnace.

The machine ensures clean metal for downstream processes, optimising performance in downstream extrusion and casting processes. The use of digital image processing cameras allows the automation of the skimming process, improving the efficiency of the process.

The efficient operation of the skimming machine minimises downtime and associated maintenance costs, reducing damage to the furnace. The autonomous operation of the machine also results in shorter door open times, reducing furnace cycle time and saving energy. Furthermore, it eliminates refractory damage and the downtime for refractory repairs.

The Smart Salt Slag Cooler maximises aluminium recovery from the salt slag produced by the tilting rotary furnace. This system cools the salt slag quickly, preventing aluminium oxidation. The salt slag is poured into a dedicated conveyor and introduced into the trommel of the cooling system, ensuring that it never gets in direct contact with the cooling water.

The Smart Salt Slag Cooler requires significantly less space for cooling compared to traditional basket systems. It is designed to maximise metal yield from aluminium while minimising energy consumption.

The GHI Smart Furnaces equipment provides greater energy efficiency and lower CO2 emissions per tonne produced, making the Smart Salt Slag Cooler an environmentally friendly choice for aluminium recycling plants. After the cooling cycle is completed, the dust and fines are transported to storage silos for further processing in salt recovery plants while coarse aluminium pieces are sent back to the melting furnace.

Our sow casting lines are fully automated, eliminating the need for manual intervention. This reduces human error and improves consistency. We have incorporated an automatic sow mould pre-drying and demoulding system into the process.

We ensure consistent sow geometry and exceptional dimensional accuracy through precise control of the casting parameters.

Our sow casting lines utilize a series of molds to cast multiple sows simultaneously. The mould number can be tailored to customer requests, and the moulds are strategically positioned on a conveyor belt. The capacity of this conveyor belt can be adjusted according to customer requirements, making our sow casting lines highly efficient and capable of producing sows with a high degree of precision.

We offer additional options such as an automatic skimming robot, an automatic printing system, and an automatic sow stack and buffer conveyor belt.

The Autonomous Charging Machine ensures consistent and repeatable charging, maximizing furnace utilization. It includes the monitoring of each load's weight for precise control and process improvement, all managed through our platform, BeyondAlea by GHI Smart Furnaces. 

The automated process significantly accelerates charging, allowing for quicker furnace cycles, decreasing heat loss, and improving productivity.

The gentle and controlled transfer of metal protects the furnace refractory lining, extending its lifespan and reducing maintenance costs.

The autonomous operation eliminates the risk of operator injuries associated with manual charging.

Applies a controlled cooling rate by forced convection with air or water to the aluminium billets and coils after hot treatment. The cooling rate, contingent on the alloy, impacts the properties of the billets during extrusion.

Engineered to decrease the coil treatment process time, thereby enhancing the overall efficiency of the aluminium recycling plant.

Capable of both controlled and non-controlled cooling of previously treated parts. Can serve as an active part of the treatment or be used to reduce the cycle time.

Equipped with a series of roof fans that blow air across the load. Adjustable flow rate cold air intakes are strategically located around the fan housing area, enabling the regulation of cold air volume based on the required cooling speed. Can be fitted with a water-cooled cooling system and is constructed from stainless steel in such instances.

Our ladles are constructed from high-quality materials and incorporate safety features to minimize the risk of spills or leaks. They are built under safety standards, with pressure and welding tests, complying with international road transport regulations, ensuring a secure transport environment for the molten aluminum.

The ladles are designed to minimize heat loss, ensuring that the molten aluminium maintains its temperature throughout the transportation process. They feature insulating and refractory coating that guarantee maximum thermal insulation.

The robust design of the ladles minimizes maintenance requirements and ensures extended service life. This results in reduced downtime, optimizing the overall efficiency of the recycling process.

The Decoating System improves the scrap recovery process, resulting in a higher yield.

The system’s operation leads to lower energy consumption during the melting process, due to the combustion of organic components in the feedstock for the process itself and metal preheating.

The load is heated up to temperatures between 300°C and 350°C, effectively removing water and oil. This process is crucial to ensure the complete removal of moisture, even after a previous spin drying process.

The load is heated up to 500°C – 550°C, effectively eliminating VOC content.

The Decoating System lowers fumes emission, making it a more environmentally friendly choice.

Our cutting saws are engineered to cut aluminium billets with high precision, ensuring consistent dimensions and minimising waste.

Our cutting saws can be seamlessly integrated with various automation systems, including weighing systems, ink marking systems, and stacking devices, to optimise billet handling and processing.

Designed for fast and efficient cutting, our saws help reduce production time and labor.

Depending on your needs and the size of the products, our cutting saws can be equipped with either circular or band blades.

For efficient management of cutting chips, our cutting saws come with a chips suction system and compacting press.

The ingot casting machines produce ingots with consistent dimensions, low surface defects.

The efficient and reliable casting process minimizes ingots rejects, reducing the environmental impact of aluminium remelting.

The fully automatic process including the furnace tilting control eliminates the need for manual intervention, reducing human error and improving consistency.

The Aluminium Scrap Sorting Equipment is designed to achieve high levels of accuracy with error rates of less than 1%. This ensures that only the highest quality aluminium scrap is used in the melting process, leading to significant cost savings in the long run.

The Aluminium Scrap Sorting Equipment can process large volumes of scrap quickly and efficiently. This reduces the time and labour required for the sorting process, leading to reduced waste and lower emissions.

The Aluminium Scrap Sorting Equipment can be configured to meet the specific needs of each recycling plant. This allows plants to optimize their sorting process for maximum efficiency.

The vertical casting process eliminates the upward flow of molten metal, resulting in billets with consistent cross-sections and reduced distortion. This process uses a cooled mould that is positioned vertically, ensuring uniformity and precision.

Our vertical casting method minimizes oxidation and inclusions, leading to billets with superior mechanical properties and reduced defects. This is achieved through direct chill casting, which produces ingots initially by containing the liquid metal in a cooled mould and then by direct cooling of the casting.

The uniform billet geometry produced by our machine promotes efficient extrusion, resulting in high-quality aluminium profiles with consistent dimensions and reduced material waste. The cooling medium is water, used both for the mould cooling (primary cooling) and the direct or secondary cooling.

Our fume treatment equipment captures and eliminates harmful by-products, including Hydrogen Fluoride (HF), Hydrogen Chloride (HCl), Dioxins (PCDD/PCDF), Sulphur Oxide (SO2), and solid particles.

Our filtration systems are automatic, with dosage and pneumatic transport of additives (lime and active carbon) to reduce harmful emissions. These systems have proven to operate for many years in the harshest environments with little to no upkeep.

The systems are designed for continuous operation and can handle varying fume levels. They can adapt to any operating specificities such as huge variations in terms of flow rate or temperature.
