Abstract

PURPOSE: To enable to directly cool red heat pellet by water, by providing pan conveyor right under recovering passage recovering reduced pellet from the secondary grizzly side and transferring the above pellet in one directio and also, sprinkling water on the pan conveyor from sprinkling pipe.
CONSTITUTION: Raw pellet sent on the conveyor 3 of the grate 1 from the raw material supply apparatus 2, is slowly calcined in the rotary kiln 7 kept at reducing atmosphere and reduced pellet is made after dried 4, dehydrated 5 and preheated 6. Next, reduced pellet is reached the secondary grizzly 9 passing on the primary grizzly 8 and is dropped on the pan conveyor 29 passing the branch chute 28 from the recovering passage 9a and then, is received in the pan 29a filled with water. Then, the above pellet is transferred in one direction and is cooled by sprinkling water from each sprinkling water pipe 29b. Generated steam is collected in the hood 29c and is disharged from the duct 29d.
