Mini Mobile Asphalt Mixing Plant

A mini mobile asphalt mixing plant is an integrated, rapidly relocatable asphalt mixture production equipment, primarily used for small to medium-sized road construction, maintenance, and temporary projects.
 

Technical Parameters and Core Configuration
1. Production capacity range
Mini asphalt mixing plants typically refer to equipment with a processing capacity of 20-80 tons/hour, such as 20 tons/hour, 40 tons/hour, and 80 tons/hour.
2. Power and fuel
Total power is generally between 23.7-300kW. Fuel options include fuel oil (diesel/heavy oil), coal, or natural gas. For example, the YLB series fuel oil models have a power of 23.7-60kW, and coal-fired models have a power of 40-90.3kW, with fuel oil consumption of 5-7.5kg/ton and coal consumption of 13-15kg/ton. Some equipment supports dual-fuel switching, such as using a diesel/heavy oil mixed strategy, reducing fuel fluctuation costs by 30%.
3. Modular design
The mobile asphalt mixing plant equipment adopts a containerized or modular structure, facilitating transportation and rapid installation. Compared to stationary asphalt mixing plants, installation time is reduced by more than 50%.
4. Environmental protection and intelligentization
- Dust removal system:
Generally adopts a two-stage process of "gravity dust removal + bag filter dust removal," achieving dust emissions below 30mg/m³, complying with EU standards. Some projects also add activated carbon adsorption to treat asphalt fumes, with benzo(a)pyrene emissions below 0.008mg/m³.
- Intelligent control:
PLC or industrial PC systems support manual/semi-automatic/fully automatic operation, with formula input, fault diagnosis, and remote monitoring functions.

Application Scenarios and Advantages
1. Typical scenarios
- Road maintenance: Rapid repair of potholes and cracks; rural road maintenance.
- Temporary projects: Short-term construction in mountainous and remote areas, supporting relocation within 48 hours.
- Small and medium-sized projects: Municipal road and industrial park road construction.

2. Core advantages
- High Mobility:
Wheeled or trailer-mounted designs allow direct road use without fixed infrastructure, suitable for multiple construction sites.
- Controllable Costs:
Initial investment is 30%-50% lower than stationary asphalt mixing plant equipment, with optimized energy consumption and maintenance costs.
- Wide Adaptability:
Can process natural sand, manufactured sand, and RAP (recycled asphalt mixture); some models have a RAP blending rate of over 30%.

3. Key selection factors
- Capacity matching:
Select models with a capacity of 8-120 tons/hour based on project scale. For long-term projects, consider medium-sized equipment to improve efficiency.
- Fuel economy:
While initial investment in natural gas equipment is higher, carbon emission benefits can cover the 8%-10% increase in fuel costs.
- After sales service:
Prioritize brands with local service centers and spare parts warehouses.
- Certification:
CE certification (EU) and EAC certification (Eurasian Economic Union) are mandatory for export; some countries (such as Saudi Arabia) require SABER certification.
- The European and American markets place greater emphasis on noise control (≤85dB(A)) and RAP (Rapid Acid Processing) capabilities, requiring customized design in advance.
 

Mini mobile asphalt mixing plants occupy an important position in the global infrastructure market due to their flexibility, efficiency, and green intelligence. Companies need to comprehensively consider technical parameters, environmental compliance, and cost-effectiveness based on project requirements to select the appropriate model and service solution.
