China Vertical Asphalt Melting Device with Stirring Mechanism - High Efficiency Suppliers & Factory Solutions
Product Description
For a relatively large melting capacity (2–15 t/h), a vertical coil structure is adopted; for a smaller melting capacity (1–2 t/h), a horizontal tube bundle structure is adopted; for a very small melting capacity (test use – 100–1000 kg/h), an electric heating structure is adopted.
Continuous melting ensures stable discharge and can operate 24 hours a day without interruption. Indirect heating combined with forced stirring eliminates local overheating and prevents asphalt performance degradation. Built-in slag discharge ensures environmental compliance.
Main Structure
Compared to the submerged pump asphalt melter, the agitated vertical asphalt melter replaces the high-temperature circulation system with an agitation system (agitator and drive unit), resulting in a more compact equipment structure, faster, more uniform and stable heating, and lower failure rate.
The main structure consists of an asphalt tank (straight upper section and conical lower section), thermal oil heating coils (inner and outer coils plus conical coil), agitation system (gear motor, bracket), support frame (upper and lower brackets and columns), and is equipped with electronic load cells, digital thermometer, bottom slag discharge mechanism, as well as an asphalt filter and asphalt buffer (receiving) tank.
Working Principle
The stirring-type asphalt melting device can make the modified asphalt neither decompose nor melt rapidly and continuously, reaching the required process temperature, and continuously and stably discharging the qualified melted asphalt.
Solid asphalt enters the melting zone from the feeding port. Under the action of the high-temperature heat transfer oil, the asphalt is heated and melted, and is stirred by the stirrer to enhance heat transfer; high-quality liquid asphalt is pressed into the secondary heating zone, and the slag enters the conical storage slag zone.
After melting, asphalt enters the secondary heating zone for further heating, dehydration, and sedimentation. When the temperature meets process requirements, qualified asphalt is continuously discharged through the filter and transported by the insulated pump.
Temperature Control: A measuring point at the outlet controls the heat transfer oil inlet valve. This regulates melting speed and prevents asphalt aging due to overheating.
Core Applications
Production of prebaked anodes; melting of coal tar pitch binder.
Supplying liquid asphalt to mixing plants, pavement repair, and crack sealing.
