Description

Technical Field

[0002] In the common asphalt mixing industry, the internal combing and lifting structure of the drying drum mostly adopts rake type or chain type. The two structures currently used are fixed inside the drum. The recycled material is lifted to the regeneration drum by the elevator. After being continuously heated by the burner and reaching a certain temperature, the asphalt carried by the recycled material begins to melt. The melted asphalt has a high viscosity and adheres to the rake chain and the inner wall of the drum. At the same time, it adheres to fine stones, forming a vicious cycle. Eventually, the drum loses its combing and lifting function, and the heating is uneven, and the energy consumption increases. It needs to be cleaned up manually in time, which is time-consuming and labor-intensive, bringing many inconveniences to production.
