  • Pneumatic conveyor
    Patent number: 9643799
    Abstract: A pneumatic conveyor is operable to convey fine material and includes a pressure vessel and a pneumatic injection port. The pressure vessel presents a chamber operable to receive fine material and to be selectively pressurized with air to pressurize and convey the fine material. The pressure vessel includes an inclined wall that extends upwardly relative to an outlet, with fine material in the chamber being collected by the inclined wall and urged toward the outlet. The injection port fluidly communicates with the chamber, with the injection port located adjacent the outlet to inject compressed air into the flow of pressurized fine material.
