Solid Asphalt Melter
The solid asphalt melter is a specialized heat exchange device. The solid asphalt material receives external heat energy through the melter, thereby increasing in temperature and melting.
Classification Overview:
- By Material: Particle asphalt melter and block asphalt melter.
- By Heating Medium: Direct heating (coal, gas, fuel oil) and heat transfer oil (including electric).
- By Structure: Vertical melter and horizontal melter.
- By Heating Tubes: Tube bundle type and coil type.
Generally, the melting capacity is large (2 to 10 t/h), and a vertical coil structure is adopted; for smaller melting capacity (1 to 2 t/h), a horizontal tube bundle structure is used; for very small melting capacity (for testing purposes to 100 to 1000 kg/h), an electric heating structure is used. For block asphalt, an intermittent (discontinuous) tube bundle structure is generally adopted.

Frequently Asked Questions
What are the main types of heating media used in these melters?
The melters can use direct heating methods (coal, fuel gas, or fuel oil) or heat transfer oil systems, which include electric heating options.
How do I choose between a vertical and horizontal structure?
Selection is typically based on capacity: vertical coil structures are used for large capacities (2-10 t/h), while horizontal tube bundle structures are preferred for smaller capacities (1-2 t/h).
What is the melting capacity range for testing purposes?
For small-scale testing or laboratory use, electric heating structures with a capacity of 100 to 1000 kg/h are commonly used.
What type of asphalt can this equipment process?
It is designed to process solid modified asphalt, including both particle forms (0-6 mm) and block forms using intermittent tube bundle structures.
What are the required heating conditions for the medium?
When using heat transfer oil, the medium temperature should typically be maintained between 240 to 260℃ with an allowable working pressure of 0.8 Mpa.
What is the expected viscosity of the asphalt after melting?
The asphalt typically reaches a viscosity of 300 to 700 mpa·s when heated to temperatures between 180℃ and 200℃.
