At the same time, the frying mechanism 3 is started. When the frying mechanism 3 is running, the vibration mechanism is started to vibrate the screening net 5, and then the corresponding aggregates are put into the screening box 4. The aggregates are screened by the vibrating screening net 5. The aggregates of the composite size fall into the frying box 2, and the aggregates with large particle sizes are screened out. The frying mechanism 3 stirs and fries the asphalt and aggregates. During the whole using process, the asphalt materials can be fried and processed, and at the same time, the aggregates with large particle sizes can be screened, reducing the situation of large void ratio in the subsequent use of asphalt materials and improving the stability of asphalt materials in subsequent use. At the same time, the road surface can be made more flat.
