The DUC discharge unit is specially designed to prevent bridging of product at the hopper outlet (up to 5 m³). A rotating paddle inside the hopper cone keeps the product in motion. When mixed products are used, the rotating blade avoids product separation at the hopper outlet. The DUC guarantees a smooth fl ow of product and maximizes the fi lling effi ciency of the component installed below the unit (e.g. a rotary valve).
