X-TRACT’s robust construction also includes a top-mounted x-ray source that protects it from dirt, preventing costly maintenance and extending the machine's lifetime. Winkler comments: “Our machine concept was built from the ground up with an extra focus on performance longevity. We offer a variety of sensor, valve and even x-ray power options to maximize throughput and minimize product loss.”
Depending on the application, X-TRACT comes with an optional x-ray power supply up to 1000W for high throughput processing of multiple materials and grain sizes, including 5 – 40 mm aluminum fines and copper wires. The machine’s software-based Dual Processing Technology offers simultaneous object and area processing of adjacent and overlapping objects, therefore eliminating the need for additional sensors.
Accelerating the Future of Green Aluminum
Recycled aluminum can be produced with less than 5% of the carbon footprint of primary aluminum. In Cisterna di Latina in Italy, the green billet foundry Indivest LT purchases post-consumer aluminum scrap from Centro Rottami. After introducing X-TRACT technology at Centro Rottami, Indivest LT has been able to more than double the amount of recycled content from 20% to between 40 and 50% thanks to the purity levels provided by X-TRACT.
Roberto Antichi, President of Indinvest LT, added: “Using the clean material from X-TRACT, we have far fewer pollutants and don’t need to clean the furnace as frequently. Cleaning the furnace involves opening the door and dropping the temperature from 1100 degrees to 800 or 900 degrees. Getting it back to 1100 degrees requires time, gas and electricity.”
With strategies like the The European Circular Aluminium Action Plan setting a clear path towards higher recycling rates and more post-consumer aluminum used in production, scrap metal operators and smelters alike significantly benefit from X-TRACT technology. It has already proven to help reduce the industry’s dependency on bauxite and other raw materials, while saving massive amounts of energy and gas during aluminum production. Last Winkler explains: “Sustainable, high-performance design is essential for both small and large operators. Preventing downtime is going to become even more critical, especially as the demand for recycled aluminum continues to grow across automotive, construction and packaging industries. It’s technologies like X-TRACT that bridge the gap and make the most of the secondary raw materials in the economy.” Today, TOMRA serves all-sized players metal recycling and smelting with X-TRACT units installed in 34 countries.
