  • Shaft furnace feed device
    Patent number: 4040530
    Abstract: The service life of the components of a bell-less shaft furnace charging installation is enhanced by controlling the trajectory of charge material delivered thereto to obtain an essentially entirely vertical discharge from a discharge funnel through a feed channel to the furnace. Also, erosion of the wall of the discharge funnel is minimized by creating an annular build up of charge material about the discharge end of the funnel, the material build up extending along the funnel wall to at least the impact region of freely falling charge material delivered thereto.
