[0003] The elastic impeller feeding device is generally composed of a rotor impeller with several blades, a bearing, a housing, a sealing device, a reducer and a motor. When in use, the fly ash falls by its own weight and fills the gap between the rotor impellers, and then is discharged quantitatively and continuously at the bottom as the rotor impeller rotates.
