Precision batch feeder for flowable ingredients
Achieve precise ingredient control with a batch feeder designed for versatile material handling, enhancing product consistency by managing varying input flows without degradation.

Accurately Doses and Feeds Varied Solid Ingredients
The FlexWall®Plus Batch Feeder from SPS | Solids Process Solutions is a versatile loss-in-weight system designed to handle a wide range of flowable ingredients, such as powders, pellets, flakes, and fibers, with precision and consistency. Utilizing a flexible polyurethane hopper paired with amplitude adjustable paddles, it ensures even screw filling and consistent mass flow without degrading material integrity. Suitable for industries such as aquafeed, chemicals, dairy, and more, it caters to diverse end-products including fish feed pellets, specialty chemical powders, and plastic granules.
The feeder features interchangeable screws and tubes that facilitate quick adjustments for varying ingredients and feed rates, making it adaptable to production needs. A high-tech weighing system provides unparalleled accuracy in batch dosing by measuring solids’ weight before and during operation. The compact trapezoidal design allows up to six units to be arranged around a central feed, optimizing space in production environments. Options like a hinged motor and separate paddle motor enable easy cleaning and handling of difficult-to-flow materials, enhancing maintenance efficiency and operational uptime.
