Adaptation to extreme cold regions
Equipment stability and low failure rate
In extremely cold regions, climatic conditions have a great impact on resource development and livelihood protection. Promoting the construction of road infrastructure plays a key role in opening up the veins for the transportation of materials and promoting the development of energy and minerals.
The road project under the extreme cold environment needs to face two systematic challenges of equipment adaptability and continuous operation, and the cold-resistant design and intelligent construction control of asphalt mixing plant have become the core technology to break through the low-temperature technology barriers. Its innovative technology system not only significantly improves the efficiency of project implementation, but also drives the sustainable development of infrastructure construction in extreme environments.

- Drying drum, asphalt pipeline, dust collector, hot material bin all the insulation layer increased to 100mm, to ensure that the temperature is up to standard.
- Increase the power of burner to meet the higher heating requirements
2.Equipment stability challenges in low temperature environments
Processing and transmission structure optimization
- Shaft hole processing precision control: adopting high-precision boring machine to process the shaft hole, ensuring the concentricity of the shaft end, reducing bearing wear and prolonging service life.
- Direct connection transmission mode: the mixing drive adopts the motor and reducer directly connected with the big shaft, avoiding the problem of unsynchronization of the traditional chain transmission and reducing the failure rate.
Simplified maintenance of screening and combustion system
- Vibrating screen low-maintenance design: 4-layer double vibrating motor linear screen structure, vibrating motor maintenance cycle extended to 1500 hours, reducing downtime.
- Automatic burner cleaning: equipped with blowing pipeline to prevent clogging of the oil circuit, reducing the frequency of manual cleaning and maintenance costs.
Drive stability and failure prevention
- Worm gear reducer: reverse self-locking function is adopted to prevent material spillage and plate chain damage in case of power failure or malfunction, and improve stability.
- Elastic tensioning device: spring buffer design reduces the risk of wear and breakage of the plate chain and reduces the failure rate.
Metering and proportioning control
- Belt machine frequency conversion coarse proportioning: through the frequency converter to realize the initial coarse metering, reduce the overflow problem caused by the proportioning error, and reduce the cleaning frequency.
3.Conflict between thermal balance and ecological protection
Closed structure and negative pressure dust prevention technology
- Totally enclosed air venting design: The air venting pipe is installed in the outer cover of the screen body, which suppresses dust from escaping through the totally enclosed structure and the negative pressure environment, and eliminates the risk of dust leakage.
- Enhanced dust proof performance: Negative pressure system ensures that the dust always flows to the inside of the hood, avoiding dispersion to the external environment and reducing the risk of pollution.
High-efficiency dust removal equipment configuration
- High-pressure pulse bag filter: Adopting pulse cleaning technology, the filter bag is instantaneously blown by compressed air to realize efficient dust removal and meet the stringent environmental emission standards.
- Environmental compliance guarantee: the dust removal efficiency is stable, effectively avoiding environmental complaints caused by excessive dust.
Core equipment selection guide
Selection of asphalt mixing plant in the cold region should focus on the stability and efficiency of the plant in the low-temperature environment: the core points include strengthening the heating system, reducing the failure rate of key components, optimizing the automation of intelligent control, as well as equipped with a modular design to facilitate rapid transfer and maintenance. At the same time, it is necessary to ensure stable fuel combustion efficiency and take into account the closed dust removal and thermal insulation design.
With stable high capacity and deep heat preservation design, batch mix asphalt mixing plant can meet the needs of large-scale continuous construction in extreme cold areas; mobile asphalt batch plant can flexibly adapt to decentralized construction scenarios through modular vehicle structure and low-temperature-resistant transmission system.
Macroad’s equipment combines intelligent control and optimization of cold-resistant structures to provide reliable solutions for asphalt mix production in extreme cold regions.
