NPE 2018 | EXHIBITION PREVIEW
reliable metering of colour premix batches into the extruder feed opening. The T35 feeder can handle free flowing and very poor flowing powders as well as fibres, flakes and other bulk materials. The company will also show an SP 100
Pure strand pelletiser from Coperion Pelletiz- ing Technology. Designed for long lifetime operation, the unit features a rugged housing to provide a sturdy cutting gap and high cut quality over the whole working width. A cantilevered bearing design is said to offer easy access and quick cleaning while options include pellet length regulation, driven upper feed roll, cutting head cooling, and transfer signal to the extruder controller. Coperion K-Tron will display a US-manufactured
ZRD rotary valve. Produced at its facility at Salina in Kansas, local production will allow the company to offer US customers a faster delivery and improved support and repair. ZRD valves are engineered for heavy-duty discharging and conveying of powder and granular materials and support pressure differentials up to 1.5 bar(g) and temperatures up to 100°C (higher temperature options are available). The company will also show its Mix-A-Lot mechanical bulk mixer. Designed for efficient, high speed homogenisation of materials, the mixer is available in three versions offering throughputs of up to 5 tonnes/h. A BSP feeder will be demonstrated on the booth
as part of a recirculating system with a 2415 receiver. It has been developed to provide gentle, precise feeding of free-flowing pellets, granules, and friable bulk materials and uses a simple rotating disc feed system to eliminate the need for screws, augers, belts or vibratory trays to convey the material. Three sizes are available, offering feed rates of 2 to 6,700 dm3
/h.

and Quality Control. Entek says it has introduced the 33mm extruder to meet demand for a machine that can handle small lots but offers more output than the laboratory machine. New mechanical design features include: self-aligning screw- gearbox couplings for fast and error-proof installation of screws; lock-and-key features on splined shafts to prevent screw timing errors; gauges for
quick monitoring of lube and cooling system running conditions; quick change strand die; robust and easily removable barrel shroud; and a tip wrench to remove tips with screws in the extruder. The company will also show a 73mm version of its twin-screw extruder for high output custom compounding, such as bio-resin production, wood- plastic composites and large lots of colour compounds. The machine is available with a 600hp motor and offers screw speeds of up to 900 rpm. Entek will highlight its screw design software with two interactive work stations allowing visitors to design screw and barrel layouts for specific applications. The software allows drag and drop functionality on all components that customers need to specify, such as barrel sections, screws and metallurgy. In addition, there is automatic calculation of remaining space on the screw shafts, as well as safeguards to prevent placement of certain elements where they do not belong. �
