ABSTRACT:
The solid materials circulating inside the drum are raised between a zone (22) in which the flame of the burner (12) is produced and a mixing zone (30) by raising vanes (18, 18') which form a dense screen of materials isolating the mixing zone (30) from the flame zone (22) as a result of the solid materials being raised and falling back down when the drum (2) is rotated. Recycled materials may be introduced into the zone (23) where the dense screen is formed.
