[0055] In the prior art, the density of the aggregate is greater than the density of the asphalt.

[0056] Further, the worker adjusts the rotating speed of the circular disc 10 by adjusting the rotating speed of the second driving device 11, so that the separation of the asphalt and the aggregate is ensured.

[0057] Embodiment five: As shown in Figure 1 , Figure 2 Figure 7 and Figure 9 , the embodiment discloses a waste asphalt recycling device, which has a structure substantially the same as that of the first embodiment, and the difference is that the first driving assembly of the embodiment comprises a first driving device 6 fixed on the shell 4, a third gear 17 is installed on the power shaft of the first driving device 6, the first inner ring plate 2 is an outer gear ring, the first outer ring plate 3 is an inner gear ring, the third gear 17 and the inner gear ring are engaged, a support frame 16 is fixed on the shell 4, the first gear 14 and the second gear 15 are rotatably installed on the support frame 16 through bearings, the first gear 14 and the second gear 15 are engaged, the first gear 14 and the outer gear ring are engaged, and the second gear 15 and the inner gear ring are engaged.

[0064] The working process and principle of this embodiment are as follows: The first inner ring plate 2 drives the drive wheel 5 to rotate around the central axis of the first inner ring plate 2 via the drive rod 22. When the drive wheel 5 contacts the inner or outer circumference of the arc plate 8, the friction between the drive wheel 5 and the arc plate 8 causes the drive wheel 5 to drive the gear rod 21 to rotate via the drive rod 22.
