weighing, dosing and packaging


Coperion K-Tron will be showing a range of bulk materials handling systems at NPE next month, ranging from unloading, feeding and pelletizing equipment through to packaging and loading systems. The company’s dual-blower Rail


Unload System pneumati- cally 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.

Henschel’s Xtreamor melt pump for compounding applications will be making its US debut at NPE


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. On the pelletizing front, the company will be showing an SP 100 EN strand pelletizer, which has a working width of 3.9 inch (100 mm) and reaches throughput rates up to 1,400 lb/hour (650 kg/hr) with 20 strands. The cutting head cover swings wide open to give full access inside, while the intake chute can be quickly removed by simply loosening two screws. All inside sur- faces are flat and smooth to minimize the accumulation of residues.


The IBP 250 FFS packaging machine provides


accurate and hygienic weighing, dosing and packaging for crystalline, granular, beaded or flaked goods. The system features a small footprint and the controls can be navigated intuitively by using a touch-screen. Optional extras include a check weigher, metal detection, bag marking and automatic cleaning. For the final stage of the materials flow, Coperion


K-Tron will be highlighting its new high-rate railcar loading technology for polymer pellets. This uses proven product spreading technology developed by Erhard Muhr of Germany to ensure high loading efficiency and capacity. It uses recoil forces to gently propel the pellets into the far corners of railcar compartments. ❙ www.ktron.com


Henschel will be showing its Xtreamor melt pump for the first time at a US exhibition. The pump has been developed specifically to increase the output perfor- mance of compounding lines while also reducing energy consumption. The design features specially developed twin-screws that can work with very low pre-pressure from the main extruder (0-2 bar). The screws gradually build up a high output pressure with the lowest possible stress and strain on the melt. The process-optimised conveying geometry is claimed


to provide energy reductions of up to 50% compared to traditional melt pumps. This is also reflected in the lower melt temperatures measured in the process. Henschel claims that the Xtreamor delivers near constant temperature and pressure levels and can improve compound quality as well as raising output levels. Henschel says that its new pump has been designed


to eliminate leaks and minimize maintenance require- ments. Cleaning is said to be simple, and the screws can be easily switched for product changeovers. ❙ www.henschel.de
