Production process of double drum asphalt station
The production process of double drum asphalt station is a complex and delicate process, which involves multiple links such as raw material pretreatment, mixture preparation, mixing, storage, and transportation. The following is a detailed introduction to the production process of the double drum asphalt station.
1. Raw material pretreatment
Storage and transportation of petroleum asphalt: As the main bonding material, petroleum asphalt needs to be stored in specialized asphalt tanks and transported to the mixer through a pumping system.
Crushing, screening, and storage of mineral materials: Mineral materials (including stones, sand, etc.) need to be crushed into appropriate particle sizes by crushers, and then separated into different particle sizes by screening equipment, and stored in their respective silos for later use.
2.Preparation of asphalt mixture
Measurement and transportation of asphalt: Based on the mix design, accurately measure the required amount of asphalt and transport it to the mixer through pipelines or pumping systems.
Measurement and transportation of mineral materials: Based on the mix proportion design, accurately measure the amount of mineral materials of various particle sizes, and transport them to the mixer through conveyor belts or lifting equipment.
3.Mixing of asphalt mixture
The core of a double drum asphalt station lies in its mixing process, which mainly consists of the following steps:
Pre mixed: Firstly, mix asphalt and mineral materials to preliminarily wrap the asphalt on the surface of the mineral materials, forming a preliminary asphalt mixture.
Double drum mixing: The pre mixed asphalt mixture enters the double drum mixer. Two rollers rotate relative to each other, further mixing asphalt and mineral materials evenly through friction and shear forces. A heating system is installed inside the drum to heat the mixture to the required temperature and humidity for construction.
Precise control: During the mixing process, the measurement and control device monitors the temperature, humidity, proportion and other parameters of the mixture in real time to ensure that the quality of the mixture meets the construction requirements.
4. Storage and transportation of asphalt mixture
Storage: The mixed asphalt mixture is transported to a storage warehouse for temporary storage, waiting to be transported to the construction site.
Transportation: Use specialized asphalt mixture transport vehicles to transport the mixture from the asphalt station to the construction site. During transportation, it is necessary to maintain stable temperature and humidity of the mixture to prevent segregation or deterioration.
5. Laying of asphalt mixture
At the construction site, the asphalt mixture is evenly laid on the road surface through the coordination of pavers and rollers, and compacted to form a solid road structure.

Summary
The production process of a double drum asphalt station is a highly automated and precisely controlled process. The quality and construction effect of asphalt mixture are ensured through the close coordination of multiple links such as raw material pretreatment, mixture preparation, mixing, storage, and transportation. As the core equipment in this process, the double drum mixer has been widely used in road construction due to its high efficiency, environmental friendliness, and stability.
