In a pelletising plant a first layer (8) of green pellets (1) is initially placed on a chain grate (4) and predried in an installation (11) before a second layer (10) of green pellets (1) is spread on the first layer (8) and both layers (8, 10) are dried in a second drying installation (13). A gaseous heat vehicle (14) flows through layer (8) or layers (8, 10) from top to bottom in both drying installations (11, 13). |
