drive powers. Correct interfacing of feeders and hoppers is essential if performance objectives such uniform draw of material over the whole of the hopper outlet is to be achieved. For uniform draw with a fully active hopper outlet, the capacity of the feeder must progressively increase in the direction of feed. In the case of a screw feeder, for

Oct 10, 2016 · A screw conveyor is designed to move material forward, generally with minimum possible power input. An ash conditioner is designed to put much more power in to shear and back mix the bulk material to ensure good mixing of the powder and water and achieve the required residense time. It is a piece of process equipment not a transfer device.
