提供することができるものである。 Therefore, the present invention provides a method for manufacturing artificial aggregate that solves these problems, and its characteristics are as follows: Large-sized raw pellets are supplied on top of the pellets, then small-sized raw pellets are supplied on top of the large-sized raw pellets, and after drying the large-sized and small-sized raw pellets in a drying oven, the pellets are placed in an ignition furnace. According to this method, during firing, the upper layer of raw pellets is made up of small particles, which has low air permeability. Fired. Therefore, even without preheating the upper layer, the firing temperature can be reached sufficiently, and a high-quality product with high strength can be obtained. On the other hand, since the lower layer of raw pellets is made of large particles, it has high air permeability and the firing time is shortened, but since preheating is applied from the upper layer, the pellet reaches a sufficient firing temperature. Therefore, the overall firing time remains the same as in the past, and high quality artificial aggregate can be provided.
