Offering innovations and high-speed sorting capability, the new X-Tract features Dual Processing Technology, which increases the capacity per meter width. Its simultaneous single object and area processing allows operators to choose between high purity and high recovery sorting. Even adjacent, overlapping, and composite materials can be instantly identified and separated using data-driven decision making.

The high-throughput sorting system features a next-generation Duoline XRT sensor with two independent line scans positioned close to the input material for high precision detection and faster processing. Due to its close proximity to the material, the sensor also effectively detects copper wires and ultra-thin objects to reduce material loss and maximize profits. Its new x-ray source offers variable power with up to 1000w supply for high-throughput processing of multiple applications and grain sizes, from large fractions to fines (>5mm).

Enhanced Capability and Flexibility

The new generation X-Tract is now capable of sorting with higher belt speeds ranging from 2.3 – 3.8 m/s, to maximize throughput and yields at the same time. To accommodate the faster belt speeds and higher throughput, Tomra designers extended the sorting chamber and added new extraction ports to remove dust and reduce air turbulence.

With improved image capturing, the new X-Tract delivers unrivaled sorting accuracy and its new intensity scale feature measures the relative thickness of objects. This eliminates the need for additional sensors and improves the detection of specific material groups like printed circuit boards.

While the previous generation of XRT metal sorting systems from Tomra offered models that varied by application, the new X-Tract is based on a modular machine concept. This gives operators the choice between high resolution or high sensitivity sensor systems and different valve blocks, but also enables more operational flexibility and easy upgrades to minimize long-term capital expenditures.

Machine trials in a production environment produce 10-30mm sized aluminum fractions with 99% purity levels.

Designed with the Future in Mind

To extend the lifetime of the machine, the designers added enhanced sensor shielding in addition to its top-mounted x-ray source to protect its most valuable components and provide extra stability. The new sorting system that separates aluminum from heavy metals and super lights in a single step even comes with a 4-Year extended warranty on the x-ray source and XRT sensor to consistently meet high-performance standards and service levels.

New X-Tract is also enabled for cloud-based monitoring, data-driven optimization tools, and remote access with the add-on Tomra Insight service. With the ability to connect to the machine through online monitoring and digital services, Tomra’s service team can identify potential issues before they arise and provide remote support to ensure low downtimes.
