  • Non-flooding belt feeder
    Patent number: 4475669
    Abstract: A continuous flow, non-flooding gravimetric belt feeder is disclosed which may be used to convey fluid-like particulate material. The feeder includes an endless belt having spaced, transversely mounted cleats. A lateral wall is provided adjacent each of the opposed sides of the cleats and extending between adjacent cleats, thereby preventing the fluid-like particulate material from flowing along the belt, and thereby enabling the feeder to discharge the material at a steady, pre-set rate.
