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

What is an 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.

componentsFunction description
Cold material supply systemStorage and transportation of aggregates of different sizes
Drying drumHeating and removing moisture from aggregates
Hot material elevatorTransport the heated aggregate to the screening system
Mixing tankMix 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 keywordsheat indexRelated 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:

TypeFeaturesApplicable scenarios
intermittentBatch production, precise proportioningHigh-grade highways, urban main roads
ContinuousContinuous discharging, high efficiencyLarge-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"

Note: The data in this article are based on industry reports and public bidding information, with the latest statistics as of 2023.
