Flexible Wall Feeder

Flexible Wall Feeder – High-Performance Dosing Technology

The flexible wall feeder is one of the most versatile solutions for accurate volumetric and gravimetric dosing of a wide range of materials. Whether you need to handle powders, grains, flakes, chips, pellets, pills, fruit pieces, or even frozen products, our flexible wall feeder ensures precise, consistent, and reliable material flow. When other systems struggle, our technology keeps delivering.

Thanks to the unique Flexible Wall Hopper design, dry bulk materials remain in constant motion. This continuous movement prevents common flow issues such as bridging and ratholing, ensuring smooth and optimal dosing performance. Many manufacturers across different industries rely on our flexible wall feeder technology for the accurate dosing of their dry ingredients.

Our flexible wall feeders can process a wide variety of ingredients with capacities ranging from 0.08 to 25,000 L/hour. Within this range, REWINZ offers six feeder variants, along with multiple screw diameters and configurations.

Each flexible wall feeder is available in both volumetric and gravimetric models and can be customized with a broad selection of options, including:

• Different screw geometries
• Nozzles and discharge accessories
• Measurement and control electronics
• Extension hoppers
• Additional application-specific modules

Loss-in-Weight System for Flexible Wall Feeders

To achieve maximum dosing precision, each flexible wall feeder can be installed on a weighing platform equipped with one or more integrated load cells. Combined with advanced control software, this configuration transforms the system into a high-performance loss-in-weight feeder with comprehensive adjustment possibilities.

Users can easily apply preset recipes, adjust dosing speeds, or enable coarse and fine dosing stages for superior accuracy and control. This makes the flexible wall feeder a highly dependable solution for continuous and batch dosing applications.
