What is an asphalt mixing plant?
Asphalt mixing plant is a key equipment used to produce asphalt mixture in road construction and is widely used in infrastructure construction such as highways and urban roads. This article will combine the recent hot topics on the Internet to introduce in detail the definition, working principle, classification and industry trends of asphalt mixing plants, and attach structured data for reference.
1. Definition and function of asphalt mixing plant
Asphalt Mixing Plant is a complete set of equipment that heats and mixes aggregates (gravel, sand), filler (mineral powder) and asphalt in proportion to form asphalt mixture. Its core function is to provide high-quality, uniform asphalt concrete for road paving.
| components | Function description |
|---|---|
| Cold material supply system | Storage and transportation of aggregates of different sizes |
| Drying drum | Heating and removing moisture from aggregates |
| Hot material elevator | Transport the heated aggregate to the screening system |
| Mixing tank | Mix asphalt, aggregate and filler evenly |
2. Recent industry hot spots (last 10 days)
Combined with search data from the entire Internet, the following are the recent hot topics related to asphalt mixing plants:
| Hot keywords | heat index | Related events |
|---|---|---|
| Environmentally friendly asphalt mixing plant | ★★★★★ | Many places have issued emission reduction policies to promote equipment upgrades |
| Intelligent control system | ★★★★☆ | AI technology applied to mixing plant production monitoring |
| RAP regeneration technology | ★★★☆☆ | The blending ratio of old materials exceeded 50%, sparking heated discussion |
3. Classification of asphalt mixing plants
According to the production process and layout method, it is mainly divided into the following two types:
| Type | Features | Applicable scenarios |
|---|---|---|
| intermittent | Batch production, precise proportioning | High-grade highways, urban main roads |
| Continuous | Continuous discharging, high efficiency | Large-scale projects, low-grade mixtures |
4. Technology development trends
1.Energy saving and emission reduction: The new generation mixing plant adopts natural gas heating and waste gas recovery technology, reducing dust emissions by more than 60%.
2.Intelligent: Remote monitoring is realized through the Internet of Things, and the accuracy of fault warning reaches 90%.
3.Modular design: The equipment disassembly and assembly time is shortened by 30%, adapting to the rapid transfer needs of the construction site.
5. Purchase suggestions
Users should pay attention to the following when choosing asphalt mixing plants:
• Production capacity (commonly 80-400 tons/hour)
• Fuel type (heavy oil/natural gas/electric heating)
• Whether it complies with the national standard "GB/T 17808-2021"
