Coperion K-Tron will show a range of bulk materials handling systems at NPE this month, ranging from unloading, feeding and pelletising equipment through to packaging and loading systems. Its dual-blower Rail Unload System pneumatically transfers pellets, powders and granular materials from railcars at rates in excess of 120,000 lb/ hour (54,000 kg/hour). Using separate vacuum and pressure blowers, the system is designed to unload


materials from the railcar at higher conveying


rates and for longer conveying distances. Coperion K-Tron’s modular loss-in-weight (LIW) feeders are designed for materials with

varying bulk density and for automated materials handling. The S100 single-screw LIW feeder offers feed rates from 0.4 to 560 ft³/hour (10 to 15,800 dm³/hour) and can handle free-flowing powders, granules, and pellets. The T35 twin-screw LIW Feeder offers feed rates from 0.04 to 88.0 ft³/hour (1.25 to 2,500 dm³/hour) and is designed to cope with floodable powders and more difficult, sticky or hard-to-flow materials. ❙ www.ktron.com


E-Plus dryers from Dri-Air Industries claim to offer faster, more complete drying of plastics, with high energy efficiency. Their parabolic tower design, special heater configuration and optimised air flow maximize moisture pickup for ultra-low dew points, faster drying, and reduced regeneration energy usage, says the company. Greater hopper insulation further improves their efficiency, even with the most challenging, hard-to-dry plastics. They are available in three sizes, with capacities of 25, 50, or 100lbs/hour. ❙ www.dri-air.com


FB Balzanelli is to exhibit its TR1200C automatic coiler, which is highly flexible and suitable for coiling a variety of pipes. Most com- monly used for corrugated pipes, PE gas and pressure pipes and PEX pipes up to 1in, the TR1200C has a compact design, user friendly functions and interface,

and fully automated real time adjustment. Highlights include: quick installation, thanks to its


compact design; 12in touch screen with diagnostic alarms; precision pipe guide to ensure a compact coil, saving on transport costs; a third-generation pneumatic strapping head design, for high reliability and efficiency; minimal maintenance; and, short payback time. ❙ www.fb-balzanelli.it


Herbold Meckesheim has redesigned its SMS Series granulators to cope with the most demanding heavy-duty size reduction applications in a single step. The machines are made with rotor widths ranging from 23.5 to 78.75in, and with drive capacities of 60-420HP. The knife design is segmental, ensuring a quick and easy exchange of the cutting tools. SMS Granulators are equipped with a third bed knife


called a deflection wedge. When the deflection wedge is removed larger, bulky items can be easily accommo- dated. Typical applications for these granulators are: heavy,


thick-walled semi-finished products in PE, PP, POM and PA; pipes with high wall thicknesses; and large purgings. ❙ www.herboldusa.com


Test equipment supplier Instron will exhibit its new Advanced Video Extensometer (AVE 2), which conforms to the rigorous ISO 527-2 and ASTM D638 standards. It is a fully-integrated device that adapts to the normal fluctuations of environmental conditions in the lab and is easily adapted to any testing machine that uses a ±10V analogue input (performance depends on the system). Designed to reduce errors from thermal and lighting variations that are common in most labs, it is the only device on the market to use the real-time 490Hz data rate while achieving a 1 micron accuracy, says Instron. NPE visitors will also see


Instron’s AutoX Automatic Contact- ing Extensometer that offers faster, more reliable and more accurate materials testing routines. Its high


accuracy and travel make it ideal for tensile and flexure testing of plastics. Meeting the


requirements of ISO 527-2, it is used to determine a variety of calculations including modulus, offset yield and plastic (non-proportional) elongation to failure. ❙ www.instron.com
