Twin Screw Feeder

The BPS Twin Screw Feeder is designed for precise batching and weighing applications. The feeder incorporates two Helixes into one hopper, creating a compact design for spaces that do not allow for multiple individual screw units. The feeder’s dual helix design combines fast, high volume filling with accurate dribble flow at the end of the cycle.
