Expansion of the Refial aluminium recycling plant
Refial, an aluminium scrap recycling company for the production of liquid aluminium and ingots, needed to expand its plant located in the province of Álava to respond to the growing demand of the market.
With the aim of increasing production at the plant we supplied a 30 t tilting rotary furnace to process low quality scrap with a high metallic performance, similar to the one installed in 2015, and a salt slag cooling system that increases the recovery of aluminium by avoiding the oxidation of the aluminium contained in the dross.
The salt slag used in the two rotary furnaces is transported via conveyor belts to the cooler. After cooling, the powder is transported to the storage silos for subsequent processing at the salt recovery plants, and the largest aluminium pieces are placed in baskets to be recycled in the furnace.
The plant is highly automated, which allows manual functions to be reduced and therefore increases safety. Thanks to its cutting-edge technology, the equipment allows for a high metal yield with high energy efficiency to be achieved in the different types of scrap.
The relationship between GHI and Refial began in 2010 with the supply of a turnkey plant with a 30 t rotary furnace, two melting towers, two 25 t holding furnaces, transport ladles and its auxiliary equipment.
- Higher recovery of aluminium contained in the dross
- Reduction in the cycle time
- Reduction in manual tasks in the plant
- High energy efficiency
- High level of automation
- Lower salt consumption
- Full integration with existing equipment
