ALUMINIUM RECYCLING PLANTAS

Fully automated aluminium recycling turnkey plants designed to obtain the highest metal yield for any kind of scrap.
At GHI, we design and supply plants for recycling and recovering aluminium from dross, including all the components required to ensure the efficient operation of such plants.
When aluminium is smelted, dross is produced that must be removed. This dross contains traces of aluminium that can be recovered by means of a subsequent melting process in a rotary furnace.

Dross containing aluminium is placed in a tilting rotary furnace, where the metal is smelted and then transferred to a holding furnace for addition of the alloying agents necessary. Finally, the alloyed metal is transferred to a casting machine for producing ingots, or poured directly into ladles for shipment by road in molten form.
GHI has developed a specific range of cutting-edge equipment for aluminium refineries. The aim is to recover aluminium from dross, supplying the market with customised aluminium alloys in both ingot and molten aluminium form.

Tilting Rotary Furnace for Melting Aluminium

Higher efficiency and lower contamination

For low-grade scrap recovery, we have developed this new concept in rotary melting furnaces which provides profitable metal yields and produces significantly lower contaminant waste than traditional models, which produce high amounts of waste salts.

Dross containing aluminium is placed in tilting rotary furnace, where the metal is smelted and then transferred to a holding furnace for addition of the alloying agents necessary. Finally, the alloyed metal is transferred to a casting machine for producing ingots, or poured directly into ladles for shipment by road in molten form.
GHI has developed a specific range of cutting-edge equipment for aluminium refineries. The aim is to recover aluminium from dross, supplying the market with customised aluminium alloys in both ingot and molten aluminium form.
The double door system in tilting rotary furnaces allows loading without interrupting the melting process.
GHI references include a 65-ton capacity rotary furnace, the largest manufactured to date worlwide.

Reverberatory Melting Furnace for Melting Aluminium

Highly suitable for melting and holding aluminium scrap. Its efficiency is based on melting aluminium scrap through heat reflected from the furnace walls and ceiling, and the convection effect through contact with the hot fumes produced by combustion.

Reverberatory furnaces can be static or tilting, can have sidewells, conventional doors or whole-wall doors for access to the entire width of the chamber. They can be fitted with porous plugs and agitation systems to optimise the quality and evenness of the molten aluminium.

Aluminium Smelter

A smelter is a furnace for melting aluminium or aluminium alloy ingots or medium size scrap. It is used both in foundries and in plants for recovering secondary aluminium. It can be added to an existing plant to increase melting capacity. Flue loading aluminium melting furnaces make optimal use of heat from fumes, and loads descend evenly to the high-temperature zone.

By using systems with a stock of baskets or stacks, and sometimes return of empty baskets, it requires minimum worker involvement for loading.

Top Loading Circular Furnace for Melting Aluminium

Circular furnace offering ideal features for mass melting of aluminium scrap and alloys. Extremely robust equipment with superb melting speeds.
The furnace opens at the top by means of a mechanism integrated with the chamber, which raises and swings out the domed lid so that scrap can be loaded in very quickly from baskets. This reduces the downtime that can sometimes occur when the dome lid is raised and swung out by a separate mechanism.

“Light Metal Age” echoes the world’s largest rotary tilting furnace, manufactured by GHI

The international press coverage of our latest rotary melting furnace, a world record in size and melting capacity, continues. This time it has been the prestigious American publication “LIGHT METAL AGE”, who has published an extensive report on our furnace, which has been previously published by the English magazine “ALUMINIUM INTERNATIONAL TODAY” and by the German publication of CECOF, “HEAT PROCESSING”.

Light Metal Age, like the other magazines, highlights in its article that GHI’s furnace not only increases the production capacity of Befesa’s recycling plant in Asúa (Spain), but it also reduces  significantly the salt consumption and improves energy efficiency in relation with the furnace that it replaces.

Also, is noteworthy the excellent geometry of this giant furnace, which greatly facilitates the processes of emptying and cleaning the slag. Another novel detail that is highlighted is the double door system, which allows the loading of the furnace while it is in operation, reducing heat losses.

The advantages of sensorization and the Beyond 4.0 platform used by GHI in this equipment are extensively explained, which allows receiving real-time information

of the furnace and which results in improvement suggestions, which promote the maintenance of the furnace for its optimum operation.

We thank these prestigious publications for echoing this important GHI installation.

Refial expands capacity with new GHI equipment


Refial, an european aluminium scrap recycling plant dedicated to the production of liquid aluminium and secondary ingots, has trusted again in GHI Smart Furnaces for the integration and supply of new key equipment of its expansion of the melting process area and the new salt-slag cooling system. Refial and GHI have been collaborating  since 2010.


One of the main challenges of the companies focused on aluminium recycling is the characterization of the aluminium scrap that they intend to process,   since depending on its composition the performance of the overall recycling process varies, and therefore the company incomes. In this regard, GHI Smart Furnaces, an European leader designing and providing integral solutions for the aluminium recycling market has designed different types of equipment that allow to recover the highest metal yield from any kind of aluminium scrap with the highest energy efficiency and performance.

Refial’s aluminium recycling plant is equipped with cutting edge technology, allowing the company to process a large range of aluminium scrap. Its productive means are made of two twin production lines in order to guarantee a “Just in time” aluminium delivery to its customers and to satisfy the  high demand of aluminium of the market.

A long-term relationship

The relationship between GHI and Refial began in 2010 with the turnkey supply of five furnaces and its auxiliary equipment.

At that time GHI supplied two melting towers, each one with a capacity of 5 tons per hour, to process aluminium alloy ingots or medium size scrap with a high metal yield and high energy efficiency due to the optimal use of heat from fumes.

The scope also included two rectangular reverberatory holding furnaces of 25 tons, specifically designed for receiving, holding, alloying and preparing molten aluminium. The open front of the furnaces, allows access to the entire chamber for cleaning and de-drossing operations, thus optimising finished product quality. The furnaces are equipped with porous plugs that homogenize the temperature and the alloy resulting in high-quality metal.

Additionally, GHI delivered one 30 tons tilting rotary tilting furnace, for low-grade scrap recovery, with its auxiliary equipment. The careful and studied design carried out by GHI on this kind of furnace, provides exceptional performance and metal yields producing significantly lower rates of undesired contaminant salt slags than traditional models.

Production increase and Salt Slag cooling System

Due to the great results obtained for the last 8 years and the current market demand, Refial has opted for expanding its production facilities and optimizing the  plant layout. To that end, Refial has trusted again in GHI agreeing a turnkey project that comprehends a second 30 tons tilting rotary furnace and a salt slag cooling system and their auxiliary equipment. The new equipment was started up in May 2019 having widely achieved all the requested performance parameters. 

The rotary tilting furnace is a twin of the previously supplied one in 2015 with a capacity of 30 tons for processing low-grade scrap. The new supplied salt slag cooling system contains the fumes and prevent the oxidation of the returned aluminium, increasing the metal recovery and drastically reducing the space required for cooling the traditional salt slag baskets.

The principle of operation of the salt slag cooling system  is based on the cooling down of the salt slag coming from the rotary furnaces, which is classified depending on the size and metal content. The cooling system is automatically fed by a fit for purpose conveyor that carries the salt slag from the rotary tilting furnaces, avoiding the use of traditional baskets.

The system triggers automatically when the emptying of salt slags of the rotary furnace stars.  The salt slags are poured over the conveyor and are transported to the inlet of the cooler feeding a trommel where they start to cool down.  The salt slag never comes in direct contact with the cooling water, which makes this system completely safe.

The trommel has two directions of rotation based on its operation mode: cooling-wise and emptying-wise. At the outlet of the trommel, the temperature of the salt slag is continuously measured to determine the proper operation mode, and hence the direction of rotation, upon reaching the target temperature. The internal side of the trommel is provided with several  buckets positioned in such a way that depending on the direction of rotation allow to keep the salt slag inside the trommel, continuing their cooling down, or to discharge the salt slag   emptying of the trommel once the target temperature is achieved.

Once the cooling cycle is completed, at the output of the trommel, the  salt slags pass through a screen which based on their size are discharged on two different  conveyors, one for dust and fines that transports them to the storage silos and other for coarse items  which convey them for its final storage on baskets.

Finally, the storage silos are provided with a vibratory discharging system including  a telescopic discharge protection sleeve with level sensors to minimize the formation of dust during the loading of the trucks for its further processing in the external salt slag processing plant.

In addition, in order to control the emission of dust, a complete air treatment system has been installed with several suction nozzles in critical points, such as cooling output and screening, conveyors and storage silo discharge.
