Concentric ring steps with different diameters and different axial heights are processed on the conical inner surface of the spreading disc of this invention. There is a gap between the spreading disc and the lower end of the retaining ring, but this invention cannot prevent asphalt deposition It sticks to the bottom of the tank and is not conducive to the efficient mixing of asphalt. It is unavoidable that it is a phenomenon of sedimentation and stratification.
