  • Apparatus for Controlling Solids Build Up in a Mixer, Submerged Flight Conveyor, Unloader or Similar Device
    Publication number: 20170015506
    Abstract: The apparatus of the present invention comprises a plurality of flexible impact elements for controlling the buildup of solids in a mixer, submerged flight conveyor, unloader or similar device. The device for use with the impact elements has at least one shaft and a plurality of rotating elements which rotate around a drive sprocket or extend radially from a shaft for moving ash or similar particulate solids. The flexible impact elements communicate with the device so as to limit or control the buildup of solids on the rotating elements, thus enabling a more efficient throughput of materials by the device.
    Type: Application

  • APPARATUS FOR CONTROLLING SOLIDS BUILD UP IN A MIXER, UNLOADER OR SIMILAR DEVICE
    Publication number: 20110103178
    Abstract: The apparatus of the present invention comprises a plurality of flexible impact elements for controlling the buildup of solids in a mixer, unloader or similar device. The device for use with the impact elements has at least one shaft and a plurality of rotating elements extending radially from the shaft for moving ash or similar particulate solids. The flexible impact elements communicate with the device as the shaft rotates so as to limit or control the buildup of solids on the rotating elements, thus enabling a more efficient throughput of materials by the device.
