Vertical Solid Asphalt Melting Apparatus - Efficient Heating Solution from China Suppliers and Factory
Solid Asphalt Melter
The solid asphalt melter is a specialized heat exchange device designed to convert solid asphalt into a liquid state. By receiving external heat energy, the material increases in temperature until it melts. This equipment is categorized based on several factors to meet specific industrial needs:
- By Material: Particle asphalt melter and block asphalt melter.
- By Heating Medium: Direct heating (coal, gas, oil) and heat transfer oil (including electric).
- By Structure: Vertical and horizontal configurations.
- By Heating Tubes: Tube bundle type and coil type.
Generally, for large capacities (2 to 10 t/h), a vertical coil structure is preferred. Smaller capacities (1 to 2 t/h) typically utilize a horizontal tube bundle structure. For laboratory or small-scale testing (100 to 1000 kg/h), electric heating structures are standard. Block asphalt processing generally requires an intermittent tube bundle structure.

Frequently Asked Questions
What types of solid asphalt can this melter handle?
The equipment is designed to process both particle and block solid modified asphalt, with specific structures available for each material type.
How do I choose between a vertical and horizontal melter?
The choice usually depends on capacity: vertical coil structures are ideal for large capacities (2-10 t/h), while horizontal tube bundles are better for smaller requirements (1-2 t/h).
What heating mediums are supported?
Our melters support direct heating (coal, gas, or fuel oil) and heat transfer oil heating, including specialized electric heating options for smaller testing units.
What is the maximum viscosity the melter can handle?
The system is optimized for asphalt with a viscosity of 300 to 700 mpa·s at temperatures between 180℃ and 200℃.
Is the equipment suitable for laboratory testing?
Yes, we offer electric heating melters specifically designed for testing purposes with capacities ranging from 100 to 1000 kg/h.
What are the operating temperature requirements for the heating medium?
For heat transfer oil systems, the medium temperature should typically be maintained between 240℃ and 260℃ for optimal melting efficiency.
