China Electric Solid Asphalt Melting Device - Suppliers & Factory for Efficient Asphalt Heating Solutions
Core Function
Typical Structure
Tank & Heating
Tank body: Vertical cylinder, carbon steel + insulation layer (rock wool / silicagel)
Electric heating elements: Built-in heating rods / tubes (stainless steel, far-infrared), bottom/side plates, and heating cables.
Internal Divisions
Feeding area: Solid asphalt input
Melting area: Main heating for melting
Insulation area: Constant temperature storage
Sludge area: Bottom slag discharge
Control & Safety
Attachments: Feed/discharge ports, level gauge, thermometer, control cabinet.
Safety: Explosion-proof equipment, overheat protection, optional stirring.
Working Principle
Solid bitumen is added from the top.
Electric heating elements directly heat, local rapid melting.
Solid blocks are immersed in liquid bitumen to accelerate melting (heat conduction + convection).
Temperature control system maintains 140–180℃.
Liquid bitumen is discharged by the lower discharge pump.
Impurities settle at the bottom and are regularly discharged.

Advantages
Application Scenarios
Electric vs. Thermal Oil Melting
Electric Heating
Uses electricity directly. Simple structure, excellent temperature control. Best for small to medium capacity and clean environments.
Thermal Oil
Complex system involving boilers and pipes. Large capacity. Suitable for continuous, long-term industrial production.
