ABSTRACT:
Particulate solids material contaminated with volatile vaporizable fluids are treated by an apparatus comprising an elongated inclined housing having a hollow conveyor screw disposed therein for rotation to move material from a lower inlet end of the housing to an upper inclined end of the housing for discharge through a bottom outlet opening. The conveyor screw is constructed from a hollow hub member having an upper open end and a lower end with a plurality of openings for conveying heat exchange pebbles or spheres from the upper end of the housing to the lower end through the interior of the hub. A combustor is disposed within the interior of the hub for generating combustion gasses which heat the conveyor screw and the heat exchange pebbles prior to entry of the pebbles into mixing with the material being conveyed through the apparatus. The pebble-material mix passes over a trammel at the outlet opening wherein the material is discharged and the pebbles are conveyed into an opening at the upper end of the conveyor screw for return to the inlet end of the housing in counterflow relationship with the combustion gasses.
