ABSTRACT:
The present apparatus for preparing bituminous mixtures, especially road construction mixtures which include broken-up road material, uses a kiln type drum through which the introduced heat and the mixture components travel in the same direction from an inlet to an outlet. Between the inlet and outlet there are five zones, namely, a feed-in zone, a mixing zone, a uniformalizing zone, a lifting and dropping zone, and a discharge zone with separate exits for vapors or gasses on the one hand, and for the finished mixture on the other hand. The uniformalizing zone is formed by overlapping components of the mixing zone and components of the lifting and dropping zone.
