Coperion K-Tron has introduced the RF400 Roller Feeder for battery manufacturing, a feeding system aimed at improving consistency in dry-electrode processing at laboratory and pilot scale.

The company says the RF400 is designed to provide uniform deposition of electrode dry blends while reducing waste and production variability. The system uses a grooved feed roller paired with a smooth scraper roller to feed material gently and consistently, helping prevent bridging at the outlet and improving distribution across the calender roller below.

The feeder supports a coating width adjustable up to 400 mm, making it suitable for lab and pilot-scale battery production setups. The company also says the unit integrates with its existing KCM-III controls and Smart Force Transducer weighing technology to enable real-time monitoring, precise feed-rate control and adjustments for changing material characteristics.

Dry-electrode manufacturing is getting a lot of attention because it promises lower energy use and less solvent handling than conventional wet coating—but it also makes material handling and uniform deposition trickier. “The RF400 will set a new standard in the industry,” said Jay Daniel, Head of R&D Feeders and Feeding Systems at Coperion K-Tron.
