Vertical Solid Asphalt Melting Apparatus – Efficient Melting Solution from China Suppliers and Factory
Solid Asphalt Melter
The solid asphalt melter is a heat exchange device. The solid asphalt material receives external heat energy through the melter, thereby increasing in temperature and melting. According to the material characteristics, it is divided into particle asphalt melter and block asphalt melter; according to the heating medium, it is classified as direct heating type melter (using coal, fuel gas, or fuel oil) and heat transfer oil melter (including electric heating melter); according to the structure type of the melter, it is divided into vertical melter and horizontal melter; according to the form of the heating tubes, it is divided into 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 is a solid asphalt melter?
A solid asphalt melter is a heat exchange device designed to melt solid asphalt materials by transferring external heat energy, raising the temperature of the material until it reaches a liquid state.
How are solid asphalt melters classified?
They are classified based on material characteristics (particle vs. block), heating medium (direct heating using coal/gas/oil vs. heat transfer oil/electric), structure type (vertical vs. horizontal), and heating tube form (tube bundle vs. coil).
Which structure is recommended for different melting capacities?
For large capacities (2 to 10 t/h), a vertical coil structure is typically used. For medium capacities (1 to 2 t/h), a horizontal tube bundle structure is preferred. For very small testing capacities (100 to 1000 kg/h), an electric heating structure is ideal.
What heating medium and temperatures does the system support?
The system utilizes heat transfer oil as the heating medium, operating at temperatures ranging from 240 to 260℃, with an allowable working pressure of 0.8 Mpa.
What are the material specifications for the processed solid asphalt?
The melter is designed to process solid modified asphalt with a feed particle size of 0 to 6 mm and a softening point (Worthington method) of 100 to 115℃.
What are the physical properties of the asphalt after melting?
Once melted, the asphalt has a viscosity of 300 to 700 mpa·s at temperatures between 180℃ and 200℃, and a density of approximately 1220 kg/m3.
