    • PROBLEM TO BE SOLVED: To solve such problems in the production of an artificial lightweight aggregate using fly ash, etc., containing unburned carbonaceous material as raw materials by conventional rotary kiln that production efficiency and thermal efficiency lower and breakage of pellets occurs.
      SOLUTION: In the method for producing artificial lightweight aggregate, burning of inflammable matter included in the aggregate raw material P is carried out using a tunnel kiln 2, and firing of the aggregate raw material P discharged from the tunnel kiln 2 is carried out using a rotary kiln 3. It is preferable that ≥80 wt.% of the inflammable matter included in the aggregate raw material P is burned using the tunnel kiln, and that burning of the inflammable matter included in the aggregate raw material P is carried out by utilizing flue gas from the rotary kiln 3.
