asphalt mixing plant
During the construction process of pavement engineering, because the engineering situation is more complicated, there are many problems that may arise. In, the asphalt mixing plant is the key equipment in the project, therefore, it should attract enough attention. Regarding the problems that may be encountered, today we will take a look at the contents.
According to our country’s experience in construction cases over the years, the operation of an asphalt mixing plant will be affected by many factors. In order to promote the quality of asphalt engineering, we will combine these production and construction experience to analyze and find the construction process The reasons for some of the problems in this section will provide you with some practical experience.
For example, one of the more common problems in the construction of equipment is the output problem. Since this problem will directly affect the construction period and other aspects of the project, after analysis, it is found that there may be several reasons for the unstable output or low efficiency of the asphalt mixing plant. Now I will share with you.
1. The raw material ratio is unreasonable. The raw material is the production step. If the raw material ratio is unreasonable, it will affect the subsequent project construction and cause problems such as the decline of construction quality. The target mix ratio is to control the proportion of sand and gravel cold material conveying, and should be adjusted according to the actual situation during production. If problems with the coordination are found, reasonable adjustments should be made to ensure the output of the asphalt mixing plant.
2. The fuel burn value is insufficient. In order to ensure the quality of construction, the quality of combustion oil should be selected and used in accordance with the prescribed standards. Otherwise, if you choose to burn diesel, heavy diesel or heavy oil because of the greed for cheap, it will seriously affect the heating capacity of the drying cylinder, resulting in too low output of the asphalt mixing plant.
3. The discharge temperature is uneven. Everyone knows that the temperature of the material will have an important impact on the quality of the material. If the temperature is too high and the temperature is too low, these materials will not be used normally and become waste materials, which will not only seriously waste the production cost of the asphalt mixing plant, but also affect its production output.
