These modular low-maintenance and user-friendly push/pull rod dischargers essentially consist of hydraulically-driven push/pull rods moving reciprocally above the floor of the bunker. When an upstream extraction device is activated, a hydraulic system automatically initiates a slow backwards and forwards reciprocal movement of several push rods arranged side by side. During this process, the special profile of the carriers transports the bulk material into an extraction device located at the end. Material from the silo is dosed in the required amounts by the discharge conveyor or by the push/pull rods themselves in conjunction with a variable capacity pump. In the case of a pull rod discharger, the hydaulic cylinders are mounted at the discharge point, whereas with a push rod discharger, they are mounted in the silo at the rear (opposite the discharge point).
