Abstract
Improvements in devices for thermally and continuously treating particles of different sizes, certain particles being smaller than the others, characterized by the fact that it is constituted by an elongated hollow body formed by an external wall that extends axially and that circumscribes a predetermined periphery to define a vertical axis furnace, the body having an upper end and a lower end, a dosing hopper at the upper end to receive the particles and load them into the body, the hopper having a series of discharge tubes that extend inside the body, the tubes adapted to introduce the smallest particles mainly along the periphery of the shaft furnace, in ring patterns surrounded by the largest particles, the tubes also being adapted to direct the majority of the largest particles closer to the center line from the shaft furnace than from the periphery of the shaft furnace to form a valley from the fall line; and means between the upper and lower end to introduce a gas in a generally inward direction and radially into the body to heat treat the particles.
