The influence of the asphalt mixing plant can not be underestimated. It also has a great influence on the heating efficiency of the asphalt conveying pipe. This is because the important performance indexes of the asphalt, viscosity and sulfur content, are closely related to the asphalt mixing plant.

In general, the greater the viscosity, the worse the atomization effect, which directly affects work efficiency and fuel consumption.

As the temperature increases, the viscosity of the heavy oil gradually decreases, so that the high-viscosity oil must be heated and heated for smooth transportation and atomization.

Therefore, in addition to understanding its general indicators, it is necessary to master its viscosity-temperature curve to ensure that the heating can reach the viscosity required by the burner before atomization.

When inspecting the asphalt circulation system, it was found that the asphalt in the pipeline solidified due to the failure of the temperature of the asphalt conveying pipeline.

The reasons for the analysis are as follows: 1. The high oil level of the heat transfer oil is too low, resulting in poor circulation of the heat transfer oil; 2. The inner tube of the double tube is eccentric; 3. The heat transfer oil line is too long; 4. The heat transfer oil pipeline is not taken. Proper insulation measures, etc., are the main factors affecting the heating effect.
