A conveyor belt runs on the bottom of the filling funnel. The conveyor belt projects into a sieve drum, which is driven by a hydraulic motor. The material is transported through the sieve drum by a helical conveying ledge. Fine-grained elements of the material fall onto a conveyor belt extending below the sieve drum and are carried out to the side through conveyor belts extending at an angle. Coarse parts of the material are carried out at the rear end of the sieve drum through a conveyor belt.Field of SearchMagnetic and siftingMagnetic and fluid suspension Aperture in circumferential wall of hollow body (e.g., tube, etc.) rotatable about longitudinal axis thereof Special application Feeding Feeding and discharging Conveyors Hoppers Conveyors Conveyors Feeding or dischargingd Rotating Multiple Nested Attached Rotating Rotating Brush | |
