Service Sani-Tri uses optical sorter to positively sort white ledger.
Pellenc ST America, Concord, Calif., has announced the startup of a Mistral MDV 2800 at Service Sani-Tri, Rouyn-Noranda, Quebec, Canada. The dual-sort machine is part of the new Mistral Dual Vision series and is equipped with near-infrared and a color spectrometer, which allows for detecting and ejecting white ledger in the fibers line.
In addition to positively sorting white ledger, the MDV 2800 also sorts metal, plastic and aseptic containers, sending them to a container line for additional processing.
According to Pellenc ST, the equipment includes the company’s Turbosorter technology, which enables high-speed feeding of fibers composed of ONP (old newspapers), some OCC (old corrugated containers), white and colored paper. It also includes a motorized roller on the split gate to help eject white ledger, the company says.
Pellenc ST says the Mistral 2800 can process up to 8 tons per hour at a sorting efficiency of more than 90 percent.
