[0035] like Figure 1-10 As shown, a continuous batching system for polymer asphalt production includes a batching tank 1, a mixing mechanism 2, a speed transmission mechanism 3, a continuous feeding mechanism 4, and a base 5. The batching tank 1 is installed in the central through hole of the base 5. The mixing mechanism 2 is movably connected inside the batching tank 1. One end of the mixing mechanism 2 is connected to a power mechanism, and the other end of the mixing mechanism 2 is connected to the speed transmission mechanism 3. The speed transmission mechanism 3 is connected to multiple continuous feeding mechanisms 4 installed on the batching tank 1 to control the multiple continuous feeding mechanisms 4 to add raw materials into the batching tank 1.

[0036] This invention discloses a continuous batching system for polymer asphalt production. During batching, different raw materials are placed into multiple continuous feeding mechanisms 4. Base asphalt is added into a batching tank 1. Then, a power unit is powered on and started. The power unit drives a stirring mechanism 2 to rotate within the batching tank 1, stirring the base asphalt. The stirring mechanism 2 simultaneously drives a speed transmission mechanism 3, which in turn drives multiple continuous feeding mechanisms 4 to operate. This allows raw materials to be added to the batching tank 1 through multiple continuous feeding mechanisms 4. Adding raw materials while the stirring mechanism 2 is operating inside the batching tank 1 improves the mixing effect between the raw materials and the base asphalt, resulting in more uniform mixing and improved asphalt processing.
