Smelting and pulverising modified asphalt producing equipment

The utility model discloses a modified asphalt producing device used for producing high molecular polymers (such as SBS, PE, etc.) for road surfaces. The utility model is characterized in that the modified asphalt producing device integrates machine, electricity, liquid and heat. The whole production process is automatically controlled by a PLC program, three devices of melting, mixing and stirring are made in the same tank body, and a through shaft is a horizontal type. Outer mixing agent is conveyed by a double-screw conveyer, and the flow capacity of an asphalt conveying pump can reach more than 30 cubes per hour. An asphalt valve is a plate type gate valve, and a shell body has no need to be provided with an interlayer to preserve heat. A smelting and pulverizing machine is characterized in that multiple dynamic and static pulverizing machines are arranged, teeth channels are provided with interlacing, the through diameters of through channels are not equal, and the through channels can be adjusted and rotated relatively. The extreme homogenization of the mixture under the condition of high-temperature decomposition is ensured, the particles are refined, and the output particle diameter of the outer mixing agent which is less than 0.015 mm can reach 97 percents.
