TOMRA Sorting Recycling installed multiple scrap sorting technologies in the new metal sorting plant at Wendt Corporation’s Technology Center in Buffalo, NY. The new Wendt plant provides demonstrations of the company’s latest technologies and processes for cleaning, sorting, and upgrading shredded non-ferrous metals, such as zorba and zurik. The center also supports the company’s research and development activities.
“Wendt introduced its new metal sorting plant at a critical juncture in the market, given the increased purity standards for a number of scrap products and inability for scrap recyclers to sell material to China,” says Eric Thurston, sales manager metals – recycling for TOMRA Sorting Recycling. “The plant output is high-quality, furnace-ready material, and it allows operations to test their material to ensure they are installing the right sorting technology to increase final product purity, maximize profit potential, and minimize investment risk.”
TOMRA installed two sensor-based sorters at the plant — COMBISENSE and X-TRACT — for metals cleaning, mixed metals sorting, aluminum upgrading, and quality control of various shredded aluminum feed material. The COMBISENSE sorts by color and shape to separate high purity metal fractions from even the most difficult feed material. It combines a color sensor with SUPPIX® image processing technology that enhances resolution levels by a factor of eight to reduce lost product yield.
X-TRACT offers high-speed x-ray transmission (XRT) with DUOLINE® technology to deliver optimal recognition of secondary resources, regardless of material density. Exceptional resolution is achieved to efficiently sort even the most varied metals mix with the smallest grain size. With XRT, customers can create a clean twitch product or separate wrought and cast packages for furnace-ready material for smelters.
In Q4 of 2018, WENDT will install a separate line featuring the combination unit of a Wendt/TOMRA FINDER with new laser object detection (LOD). Introduced in early 2018 to help operations meet stringent standards like China’s National Sword, the LOD mounts to the FINDER platform in order to boost a circuit’s sorting capabilities without requiring additional floor space. Using laser technology, LOD identifies black objects attached to metal material detected by the FINDER’s EM3 sensor. LOD allows black rubber, glass and plastic to be separated from zorba and zurik products, which enables these commodities to be turned into a cleaner, more valuable revenue stream.
