ABSTRACT:
Apparatus is disclosed for moving particulate material such as alumina toward an outlet to a container while minimizing dispersion of dust into the atmosphere. The apparatus includes at least one coil spring which is disposed generally horizontally in the container with one end anchored to the container and the other end, which is disposed near the outlet, connected to a lever arm and crank for cyclically extending and contracting the spring. Such cyclic extension and contraction of the spring moves or at least encourages the flow of the particulate material to the outlet for gravity discharge therefrom and essentially eliminates problems of bridging and rat holes in the material.
