the patented product "local asphalt heating device" is configured to continuously produce high-temperature asphalt with a daily output of more than 300 tons.

Adopt the "ultra-low liquid level oil extraction" technology to take the asphalt at the bottom of the tank as much as possible.
All round heat preservation, temperature reduction less than 1 ℃ /h (external temperature greater than 20 ℃)
the microcomputer management system realizes the automation of storage, calculation, equipment monitoring and management.
