Thus, during feeding, along with the movement of the feeding device 200, the third raw material 132 is laid on the third blanking region 230 of the feeding device 200 through the third feeding channel 130 to form a material layer, when the third raw material 132 passes through the first blanking region 210, the first raw material 112 is laid on the material layer of the third raw material 132 through the first feeding channel 110, and similarly, the second raw material 122 is laid on the material layer of the first raw material 112, thereby realizing multi-layer material distribution. In this example, the fuel layer may be one layer or multiple layers, and the fuel layers may achieve better sintering effects.
