Auto Sort PET Bottles from Trays At NPE2018, Tomra Sorting Inc., W. Sacramento, Calif., unveiled the new Sharp Eye technology that separates PET bottles from single-layer PET trays. This enhances the previous capability of Tomra's Autosort machine to separate multilayer trays. The company says this breakthrough is commercially significant because small but critical differences in the chemical properties of PET food trays and PET bottles mean that they must be separated for equivalent-product recycling. Additionally, artificial intelligence embedded in Tomra systems also enables seamless analysis of sorted products, making future plants even smarter. The key to this innovation is an enhancement of Tomra's Flying Beam sensor tech- nology. As the first near-infrared scan system with point-scanning (eliminating the need for external lamps), this focuses only on the area of the conveyor belt being scanned. Allowing a wide range of calibration possibilities, this can distinguish even the finest molecular differences in materials flowing down the recycling line. Combined with Tomra Sharp Eye technology that introduces a larger lens for higher light intensity, it is possible to detect even the most difficult-to-distinguish properties. 916-388-3900 • RECYCLING/SCRAP RECLAIM RECYCLING/SCRAP RECLAIM Pallmann Industries, Clifton, N.J., showcased at NPE2018 its PLMW Turbo-Finer, a high- capacity size-reduction machine for producing extremely fine powders from soft to medium-hard materials. Material is metered into the Turbofiner, pre-dispersed in the high-turbulence air stream, and evenly distributed at the circumference of the pre- size-reduction zone. The material flows though the vertical grinding chamber of the Turbofiner spirally from below to above, passing through several micro- whirl zones with increasing intensity of the air whirls. The material is reduced in size by impact with the grinding path and with other material particles in the micro whirls occurring behind the beater plates of the high-speed turbo rotor. 973-471-1450 • High-Capacity Machine Produces Fine Powders The LMI5500 Series melt flow indexer from Dynisco, Franklin Park, Mass., boasts a more compact footprint, "ground-breaking accuracy" and a unified software platform between all laboratory and online production equipment. The LMI5500 is said to bring a new level of ease of use with its easy-to-clean, removable inspection plate; increased access for sample cutting (with a mirror to help view the die area); and revamped, intuitive touchscreen. This enables processors to obtain detailed analytics of lab and production data globally on a single dashboard. Features of the LMI5500 Series, which debuted at NPE2018, include: • New Windows 10 IoT interface; • Built-in WiFi, Ethernet and Bluetooth, plus multiple USB ports; • Direct digital scale USB interface for sample weighing; • Digital encoder for use in B, A/B, and intrinsic viscosity (IV) correlation. • Gravitational correction feature takes into account the lab's geographical location. 508-541-9400 • TESTING Melt-Flow Indexer Links Lab, Production Machinery Reduce scrap and improve quality with Per-Fix ® specialty flaw repair coatings.
