What machinery is used to produce asphalt? ——Comprehensive analysis of asphalt production equipment and process flow
Asphalt is an important material for road construction, and its production process involves a variety of special machinery. This article will combine the hot topics and hot content on the Internet in the past 10 days to give you a detailed introduction to the machinery and equipment, technological processes and market dynamics required for asphalt production.
1. Core machinery and equipment for asphalt production
| Device type | Main functions | Typical model |
|---|---|---|
| Asphalt mixing plant | Mix aggregate, filler and asphalt in proportion | LB3000/LB4000 |
| Aggregate drying drum | Remove moisture from aggregates | Φ2.2×12m |
| Asphalt heating tank | Heating and storing liquid asphalt | 50-100 tons capacity |
| Vibrating screen | Classification and screening of aggregates of different particle sizes | 3-5 layers of screen mesh |
| Dust removal system | Handling dust from production processes | Bag type/wet type |
2. Recent industry hot data
| Hot content | attention index | Geographical distribution |
|---|---|---|
| Environmentally friendly asphalt production equipment | 92.5 | East China, North China |
| Intelligent control system | 88.3 | Nationwide |
| Mobile asphalt mixing plant | 85.6 | Midwest |
| Recycled asphalt technology | 82.1 | first tier cities |
3. Asphalt production process
1.Aggregate pretreatment: Aggregates of different particle sizes are graded through a vibrating screen and then sent to a drying cylinder to remove moisture.
2.Measuring ingredients: The dried aggregate is measured according to the proportion through the weighing system.
3.Asphalt heating: The asphalt is heated to 160-180℃ in a special heating tank
4.Stir to mix: Aggregate and hot asphalt are fully mixed in the mixing tank
5.Finished product storage: The mixed materials are transported to the finished product warehouse or loaded directly into the truck
4. Things to note when purchasing equipment
1.Capacity matching: Select equipment with appropriate capacity according to project needs (80-400 tons/hour)
2.Environmental performance: Give priority to equipment equipped with complete dust removal and exhaust gas treatment systems
3.Energy consumption index: Compare the fuel consumption rates of different equipment (usually 6-8kg/ton)
4.Degree of intelligence: Modern equipment should have functions such as automatic temperature control and fault diagnosis.
5. Asphalt machinery market trends in 2023
| trend direction | Market share | annual growth rate |
|---|---|---|
| Environmental protection upgrade | 45% | 12% |
| Intelligent | 32% | 18% |
| mobile device | 15% | 8% |
| Regenerative technology | 8% | 25% |
As the country continues to invest in infrastructure construction, asphalt production equipment is developing in a more environmentally friendly and intelligent direction. It is recommended that purchasers should not only consider the initial investment cost when selecting equipment, but also pay attention to the full life cycle operating costs and environmental compliance of the equipment.
