Asphalt hot recycling plant is mainly used to process reclaimed asphalt pavement: the reclaimed asphalt are screened, heated, stored and weighted, then added into asphalt pavement recycling equipments to mix with virgin materials, so as to produce high quality asphalt mixture.
Our company adopts European new technology to research and develop patented asphalt hot recycling plant. This product is stable, advanced, safe and precise; the largest hot recycling asphalt proportion can achieve 50%. Our asphalt hot recycling plant will be your best choice and is able to bring you large economical benefit.

1. Cold burden system
Two sets of independent cold feeders with single capacity of 18 tons.
2. Belt feeder
Adopts frequency control and hopper door to double control the feed flux; conveyor belt with flanges to prevent the mixture from overflowing.
3. Charging belt conveyor
Equipped with feed scraper and emergency cord switch.
Equipped with a set of cold aggregate vibrating screen to prevent big charges and sundries
4. Heating system
Adopts downflow heating system to prevent the asphalt from aging and overfiring.
5. Burner
Imported Italian burner, using compressed air atomization.
Special burning fire, light oil and heavy oil are both available.
Equipped with heavy oil preheating system.
Temperature control of recycling aggregate drying: adopts imported infrared thermometer to control the temperature in ± 50°C.
6. Hoisting mechanism
Adopts abrasive bucket chain hoist which is equipped with backstop device.
7. Hot aggragate bin
Large capacity, adopts imported sensor to control the continuous material level. Imporetd infrared thermometer is installed.
8. Hot recycling aggragate weighing hopper
Adopt imported sensor to control the measurement. Precision can achieve national standard. Imported cylinder and electro valve are used in measuring and dumping.
Transition cabin, weighing hopper and chute all adopt heat transfer oils to heat and preserve. Therefore, the recycling aggragates flow fluently.
9. Dedusting System
Induced-draft dedusting device: adopts Italian fan which can effectively prevent lampblack from touching fan blades. In order to meet the environmental requirement, cold smoke exhausted by hot recycling drying drum will not directly discharged into environment but will carry on secondary combustion in the drying drum to eliminate harmful exhaust gas.
10. Control System
Asphalt hot recycling system adopts no button operation, which can achieve automatic and manual operation.
Dynamic display of process flow, human interface, fault alarming display system.
Main electric elements adopt internationally famous brands. PROFIBUS standard technique is used to ensure the convenient interface of various types of asphalt recycling devices.
