K2019 PREVIEW | MACHINERY AND EQUIPMENT
Right: Buss will launch two new larger additions to its latest Compeo kneader line, which now offers 55, 88 and 110mm diameters
Buss will introduce its Compeo 88 and 110 compounders at K, extending the scope of application for its latest generation of kneader extruders. Together with the Compeo 55, which was launched last year, the new models take the Compeo family to three, each of which can be supplied with process lengths from 13 to 25 L/D. The company will show a Compeo 110 model on its stand configured with an 18 L/D screw. The 110mm diameter machine provides an approxi- mate throughput of 1,200-2,400 kg/h (the Compeo 55 offers 150-300 kg/h and the Compeo 88 600-1,200 kg/h). It will be equipped with a down- stream side feeder and the company’s new conical twin screw discharge unit. In this configuration, the system is said to be well suited to compounding of filled and reinforced thermoplastics – including natural fibre and bio-based formulations–as well as – production of HFFR cable compounds. Configured with a 25 L/D screw, the Compeo 88 machine is said to be a good choice for com- pounding black or coloured masterbatches. For such applications, it can be fitted with one or two additional side feeders. Buss says a European masterbatch manufacturer took delivery of a Compeo 88 in the run-up to the show. Buss claims that the Compeo compounders

provide high-intensity mixing and can handle high filler contents with precise control of the tempera- ture of the compound. The machines use a modular design, which allows cost-effective configuration of optimised lines. Typical applications can range from production of thermally sensitive thermosets to demanding engineering polymers with processing temperatures of up to 400°C. One of the key features of the Compeo kneader design is its ability to combine conventional three or four-flight kneading elements with new ele- ments comprising two or six flights and to place them in any desired position within the process section. Combined with increased specific torque,
the company says this allows longer mixing zones to be used without an increase in
energy input. �

Brabender and Brabender Messtechnik will show their latest solutions for lab scale processing and rheology measurement, including a first showing for the TwinLab-C 20/40 standalone twin-screw extruder. Featuring a modular design that can allow it to be used for a wide variety of applications, it will be equipped with the Brabend- er web-based MetaBridge software. This provides ease of operation via a touch screen and enables simultaneous retrieval of measurement results via various desktop and mobile devices. Also new to Brabender’s product portfolio is the MetaStation. This torque rheometer can be used as a drive unit for various measuring mixer and extruder attachments. Other items on display include the AQUATRAC station, which can deter- mine water content precisely using a capacitive water-selective dew point sensor (meaning no chemicals or consumables are required). �

Coperion and Coperion K-Tron will present the latest developments in their compounding and materials handling product lines. Coperion will show two redesigned versions of its high-end ZSK twin screw compounders, a new SP series strand pelletiser and demonstrate its energy-efficient FluidLift ecoblue pneumatic conveying technology. Coperion K-Tron’s new introductions include a redesigned K3 vibratory feeder. The re-designed ZSK Mc18
extruders on display
will include 45 and 70 mm screw diameter models, both offering specific torque of 18 Nm/cm3
.
Mechanical and electrical features on these updated models have been optimised to enhance operation and improve efficiency, according to Coperion. Both will be equipped with ZS-B Easy side feeders and ZS-EG Easy side devolatilisation units, which are claimed to significantly speed up mainte- nance processes by enabling fast removal and reinstallation on the process section for
