A different size of contamination is extracted in each section of the installation via a combination of scalping rolls, air knife separation, diamond roll beds and individual gravimetric separators. didn’t meet their requirements, which forced the company to look for another solution. Bells toured two ClassiCleaner installations in Europe — one in France, and another in Ireland. He was impressed with what he saw. “Europe does an excellent job of recycling everything,” Bells says. But the pellet operation has unique demands. The ClassiCleaner was commissioned in December after a 24-week project involving PacBio, Dieffenbacher and local firm, International Quest Engineering. One of their challenges was to install the system while the plant continued to operate 24-7. The entire system is housed in three separate towers connected by a series of conveyors. A different size of contamination is extracted in each section, via a combination of scalping rolls, air knife separation, diamond roll beds and individual gravimetric separators. A few weeks into operations, PacBio ran into challenges with the heavy particle separation unit. Dieffenbacher is re-engineering the scalping screens to reduce the amount Canadian BIOMASS 11
