Clean foil fractions at high throughputs – UniSort Film

The UNISORT Film for optimum sorting results

Clean foil fractions at high throughputs - UniSort Film

UniSort Film

Plastic foils are among the most important raw materials for recycling and are already reused to a substantial extent. However, thanks to new technologies, much higher recycling rates will be achieved in future.

Heavy demands are imposed on today’s sorting systems deployed in the recycling industry. As plant capacities are ever-increasing as per their throughput rates, specifications are becoming more and more stringent as applied to sorting performance expectations. These aspects have an impact on sensor technology as well as on machine sorting functions. In addition, users of processing and sorting plants are constantly required to respond to improved recycling rates whilst being called on to reduce the overall volume of waste following processing.Sensor technology potential in the recycling sector – or to be more precise, detection of the wide variety of different plastic materials emanating from different material-flow sources – have remained largely untapped to date. The application of new technologies provides far better results than have been seen in the past.
The innovative UniSort Filmfrom STEINERT Group has been designed specifically for improving the product potential for this sector.

The UNISORT Film has succeeded in developing the state-ofthe-art Active Object Control-System (AOC), originally developed for fine-product sorting on the UNISORT Flake range for larger particle sizes. As in the case of small objects, the sorting of buoyant flat objects is governed by the motion behavior of the material being sorted in terms of material detection and ejection – having a substantial impact on purity and efficiency. AOC is a stabilisation system catering for defined motion paths controlling the material sorted, hence delivering a distinct improvement in quality of the final product. Stable motion of the objects even at double conveying speed results in higher throughput rates while enhancing efficiency of the system.
As on all NIR systems produced by UNISORT, the UNISORT Film system is equipped with ultra-modern HSI (Hyper Spectral Imaging) camera technology, ensuring an exceptionally high degree of flexibility and future sustainability.

Fields of Applications
On account of its light weight and high space occupancy, plastic film sorted on a standard sorting machine is hindered by restrictions and reduced conveyor speeds. The AOC system engineered by RTT STEINERT, and applied to the UNISORT Film, facilitates considerably higher throughput rates combined with improved sorting quality. This is the only way of sorting buoyant objects, such as film, on feasible lines at all. UNISORT Film is universally suitable for all functions involving the sorting of air worthy objects, e.g. paper and film, including agricultural film.

Automatic sorting of the film fractions with significantly higher throughput rate and substantially improved sorting results compared to standard machines not equipped with AOC. UNISORT Film opens the door to sorting functions hitherto incapable of being implemented economically applying standard technology.
