China Suppliers Factory Vertical Solid Asphalt Melting Equipment for Efficient Heating and Insulation
Solid Asphalt Melter
The solid asphalt melter is a high-efficiency heat exchange device designed to convert solid asphalt materials into liquid form. By receiving external heat energy through the melter, the material's temperature increases until it reaches a complete molten state.
Material Classification
Divided into particle asphalt melters and block asphalt melters based on material characteristics.
Divided into particle asphalt melters and block asphalt melters based on material characteristics.
Heating Methods
Available in direct heating (coal, gas, oil) and heat transfer oil types (including electric heating).
Available in direct heating (coal, gas, oil) and heat transfer oil types (including electric heating).
Structural designs vary between vertical and horizontal configurations. Depending on the heating element form, units are classified into tube bundle types and coil types. Generally, a vertical coil structure is preferred for large capacities (2 to 10 t/h), while horizontal tube bundles suit smaller requirements (1 to 2 t/h). For laboratory testing (100 to 1000 kg/h), electric heating structures are utilized.

Frequently Asked Questions
What types of solid asphalt can be processed?
The melter is designed to handle both particle and block solid modified asphalt, with specific structures like tube bundles optimized for block materials.
How do I choose between a vertical and horizontal melter?
Vertical coil structures are typically used for large-scale operations (2-10 t/h), whereas horizontal tube bundle structures are ideal for smaller capacities (1-2 t/h).
What heating mediums are compatible with these melters?
Our melters support various heating mediums including heat transfer oil, electric heating, and direct heating using coal, fuel gas, or fuel oil.
What is the typical viscosity of the asphalt after melting?
After the melting process, the asphalt typically reaches a viscosity of 300 to 700 mpa·s at temperatures between 180℃ and 200℃.
Is there a solution for small-scale testing or laboratory use?
Yes, for very small capacities ranging from 100 to 1000 kg/h, we provide specialized electric heating structures designed for testing purposes.
What is the maximum working pressure for the heat transfer oil system?
