China Asphalt Melting Device with Stirring Mechanism - High Efficiency Factory Supply for Road Construction and Waterproofing
Product Description
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:
- Asphalt tank (straight upper section and conical lower section)
- Thermal oil heating coils (inner, outer, and conical coils)
- Agitation system (gear motor, bracket)
- Support frame (upper and lower brackets and columns)
- Electronic load cells and digital thermometer
- Bottom slag discharge mechanism, filter, and buffer tank
Working Principle
The stirring-type asphalt melting device ensures modified asphalt neither decomposes nor melts rapidly and continuously, reaching the required process temperature while maintaining stable discharge.
1Melting Zone: Solid asphalt enters the melting zone where coils supplied with heat transfer oil melt the material. The stirrer enhances heat transfer for uniform heating. Liquid asphalt moves to the secondary zone while slag settles in the conical zone.
2Secondary Heating: Asphalt enters the secondary zone for further heating, dehydration, and impurity sedimentation. Once temperature and levels meet requirements, qualified asphalt is discharged through a filter to storage tanks.
3Cleaning & Maintenance: A bottom discharge valve and manhole allow for easy cleaning of settled impurities and internal maintenance. Impurities are discharged repeatedly until clear.
4Temperature 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.
