The asphalt regeneration annex produced by Nanqiao Road Construction Machinery Co., Ltd. adopts thermal regeneration and can be adapted to intermittent asphalt mixture mixing equipment of 1000-3000 types with a production rate of 80t/t-240t/h.
The proportion of old materials added can reach up to 60%. Seamless integration with the matching intermittent asphalt concrete mixing equipment, high measurement accuracy, coordinated control, ensuring the high quality requirements of recycled mixtures.
The use of hot flue gas reuse method can effectively solve environmental problems and save energy through secondary combustion of the generated exhaust gas.
This equipment is mainly aimed at the asphalt milling material generated during the renovation of highways, which can play a role in resource reuse, while solving the waste and secondary pollution caused by asphalt milling material, reducing production costs, and creating higher economic value for users.
This equipment adopts a special process to effectively prevent the adhesion of hot materials while heating the asphalt milling material.
Technological process:
Asphalt milling material is transported from the batching hopper to the drying drum via a conveyor belt. After heating, it is metered and sent to the mixing tank by a special device to be mixed with new aggregates, mineral powder, and asphalt, and finally becomes true asphalt recycled material.
Characteristic:
Independent system, convenient for adding to existing mixing plants.
Modular structure, easy to disassemble and assemble, short installation period.
The heating temperature is high, reaching over 160 ℃.
High production efficiency, with an addition rate of up to 50% of the total output.
Widely applicable, can heat ordinary asphalt and modified asphalt.
Comparison of Production Costs (Taking the Chinese Market as an Example)
(Set to use for 10 hours a day, with a production capacity of 200 tons/hour, or 2000 tons/day):
1. Pure use of new materials: (asphalt consumption of 4.5%, fuel consumption of 6.5kg/t finished material)
Asphalt usage per day: 2000 tons x 4.5%=90 tons
Daily fuel consumption: 2000 tons x 6.5 kg=13 tons
Asphalt market price: 4500 yuan/ton
Fuel market price: 4500 yuan/ton
Daily cost: 90x4500+13x4500=463500 yuan
2. Using asphalt thermal regeneration equipment: (asphalt dosage 2%, fuel consumption 9.5kg/t finished material)
Asphalt usage per day: 2000 tons x 2%=40 tons
Daily fuel consumption: 2000 tons x 9.5kg=19 tons
The total power has increased by 244kW, with an efficiency of 80%,
200kWx10 hours=2000 kWh of electricity x 1 yuan=2000 yuan
Three more personnel have been added, with a daily salary of 60 yuan, which is equivalent to 180 yuan for 3x60
Daily cost: 40x4500+19x4500+2000+180=267680 yuan
Daily cost savings: 463500-267680=195820 yuan
Saving per ton of material: 195820/2000=98 yuan
Note: The above parameters are for reference only and may vary depending on changes in asphalt and fuel prices, as well as differences in milling materials.
