K2019 PREVIEW | MACHINERY AND EQUIPMENT
Right: The Coperion K-Tron K3 series vibratory feeder will be demonstrated for the first time in Europe
cleaning or screw changes with just a few hand movements. The new machines also use single-part heat insulation covers in place of the traditional three-part designs. The new covers are said to be easier to handle and can be detached without removing the cartridge heaters. The ZSK 70 Mc18
will be shown
with a K3-ML-D5-V200 vibratory feeder and a ZS-B Easy siude feeder with a K-ML-SFS-BSP-100 Bulk Solids Pump (BSP). The ZSK 45 Mc18
will be equipped with a gravi-
metric K2-ML-D5-T35 twin screw feeder and ZS-B Easy with a K-ML-SFS-KT20 twin screw feeder for high accuracy feeding at low feeding rates. Coperion Pelletizing Technology will show a dual
Below: Coperion Pelletizing Technology’s SP240 model features a redesigned cutting chamber
bearing SP 240 strand pelletiser, which the com- pany says has also been reworked to simplify handling. It incorporates a new cutting tool-free gap adjustment technology that is said to make fine adjustments simpler, faster and more precise. It can also help reduce maintenance downtimes. The cutting tools are now installed closer to each other to enable a shorter unguided strand length in the pelletiser, which gives better cutting results especially with soft materials. This new arrangement also results in less dead space which, together with optimised edges and fewer free surfaces, provides improved cleanability. The complete cutting area is also accessible without tools for cutting unit exchange. Other changes include a straight intake that allows feeding of the strands without deflection as well as improved sound-proofing. Coperion K-Tron’s redesigned K3 Vibratory Feeder line will be getting its first showing in
Europe. The K3-ML-D5-V200 vibra- tory feeder will be demonsrated as part of a recirculating system with automatic refill provided by a P-Series vacuum receiver and a compact vacuum pump.
Vibratory feeders are said to be a good choice for feeding recycled
material or flakes as well as for the addition of glass fibre in compounding processes as there is no wear on me- chanical components, near eliminating maintenance. The key new feature of the K3 models is the replacement of the conven- tional rubber or spring shock absorbers with a
flexible pendulum technology. This ensures movement only in the direction of motion, rather than the more usual 360° agitation. Internal sensors measure acceleration, displace-
ment, load, current and temperature at up to 25,000 times per second while a fast-acting controller adjusts the vibratory drive signal to main- tain clean sinusoidal displacement for optimal mass flow. The combination of the pendulum drive technology with Coperion K-Tron’s SmartConnex control system also results in optimised energy consumption. The company says power consump- tion can be as low as 20W for feed rates as high as 6,000 kg/h. Coperion K-Tron will also show an SWB-300 weigh belt feeder. This simply-constructed gravi- metric feeder is said to provide reliable and highly accurate control. The company says feeders of this type can reliably handle large volumes of bulk materials with various flow properties, making them suitable for processing of a wide variety of materials, including recyclates. A FluidLift ecoblue pneumatic conveying
process for plastic pellets completes the Coperion display. The company claims that, compared to conventional systems, the FluidLift technology results in less abrasion of the pellets so helps to keep dust or strand formation to the minimum. Energy consumption is also reduced. �

Farrel-Pomini will be exhibiting together with parent company HF Mixing Group with the centre point of its display being a compounding tower system with live Synergy Control. Key features of the control include touchscreen control of feeding, integrated control of upstream and downstream equipment, automatic start-up and shutdown of all equipment, and remote monitoring and support tools. The company’s stand will also include several
