facturers face increasing challenges in ensuring the precise and reliable delivery of the electrode blend directly into the calendar gap in dry battery electrode coating processes. The RF400 addresses these challenges by
offering a state-of-the-art feeding system that provides consistent material distribution, reduces waste, and improves overall production efficiency by using advanced roller technology. The RF400 is perfectly suited for use in laboratory and pilot scale production environments, and integrates seam- lessly with existing KCM-III controls and Smart Force Transducer (SFT) weighing technology, ensuring high accuracy and reliability.
Passing through Nitrogen closed-loop systems are gaining impor- tance as they prevent dust or gas explosions through inertisation, to inhibit oxidation processes, such as the quality degrading yellowing of PTA, and to protect hygroscopic bulk materials from moisture ingress, which is essential for process stability, particularly in PA spinning plants. Coperion develops customised and optimally designed solutions with the aim of generating added value for the customer, and the process design of a nitrogen closed-loop system comprises several core components. The pneumatic conveying of bulk materials
through pipes offers advantages over mechanical systems including flexible installation, low space requirements, and minimal maintenance. However, conventional dilute phase systems have limits, especially when conveying highly abrasive glass fibre pellets. These pellets are transported at high air speeds, which often leads to problems such as the formation of angel hair and wear on the pipe bends. Glass fibre-reinforced pellets with a propor- tion of 30% to 50% also mechanically wear down the pipe material and can lead to leaks. A solution is also provided by Swiss group
Gericke in the shape of its PTA pneumatic dense phase conveying system, where a pressure vessel is used as a feeding device which doses the product into the pipeline and acts as a gas-tight valve. Small product plugs are formed in the pipeline, which are gently transported by compressed air at low speed. The conveying speed is significantly reduced compared to dilute phase conveying, which minimises wear while the pressure vessel ensures gas-tight feeding and enables the conveying of abrasive or sensitive materials. The bulk material is pushed through the pipeline in compact plugs, which increases throughput and minimises the required air consumption. For longer conveying

distances, additional air nozzles can be integrated. Many bulk material processes require defined
and reproducible particle sizes. The Gericke GNB 250 Nibbler offers the advantages of the estab- lished GNB series for smaller throughputs in a compact industrial deagglomerator and coarse size reduction grinder. Despite its compact size, the GNB 250 achieves high throughput rates and can easily be installed into existing processes making it the perfect successor to the older Gericke Nibbler series NBS 200/200 and NB 300/350. The Gericke GUC-F Universal Controller delivers
precise, reliable control for feeding, dosing, batching, and weighing, combining industrial robustness with the connectivity and flexibility demanded in applications. Its modular design and intuitive interface make it the ideal solution for both new installations and upgrades while key advan- tages lie in its versatility and scalability. One unit can control up to four feeders, supporting both gravimetric and volumetric modes for batch or con- tinuous production. This reduces equipment costs and simplifies setup, while its flexible architecture allows users to add additional feeders.
Power play Late last year,Conair unveiled the new PowerFill Pro conveying system, which combines the essentials of a small, central conveying system (vacuum pump, dust collector, and intelligent, touchscreen control) in a compact and portable cabinet. The successor to the PowerFill 8, the new
PowerFill Pro offers more power and configurabil- ity, and new pump options to deliver throughputs up to 7,000 lbs/hr over distances up to 300 ft. Featuring all-new control hardware and a 4-in
touchscreen that incorporates Conair’s common control user interface, the system serves up to eight material receivers through flexible vacuum convey- ing hoses, line valves, manifolds or other conveying hardware.
It can be equipped with any of four vacuum September 2026 | FILM & SHEET EXTRUSION 25
