Remixer with 1350 rpm idling engine hot in place asphalt recycling machine wiht 2830L diesel tank
XITONG ARHR5120-5120A model HOT-IN-PLACE ASPHALT RECYCLING TRAIN1
I.Hot in-place recycler equipment technology features:
1, Reduce traffic jam
2, Much more less transport vehicles
3, Close limited-distance lane
4, Maintain the normal traffic
5, The traffic can be opened when the road surface temperature is below 50℃
6, Fast construction speed, construction amount per day could reach up to more than 2KM of a single lane
7, Use diesel as the fuel, generate hot air by atomizing burning in the fuel chamber, air induced by the draught fan to the cover and heat the pavement ,the cover and the original pavement make up a closed space ,hot-afterwind after heating the pavement will be recycled again through the draught fan to the combustion chamber and been heated again, making full use of the heat energy.
Combustion chamber, the cover and the pavement effectively form a closed hot recycled system, achieving high efficient pavement heating.
8,Hot air temperature adjustable:350℃--550℃ be adjustable according to need at any time.
Fuel saving, low energy consumption: recycled using of hot-after-wind greatly reduces the energy ,making efficient use of fuel.
Soft heating method, low construction aging:350℃--550℃ hot air.
Heating, is a kind of soft heating method, making the lowest asphalt aging ,ensures the quality of recycled pavement
Convenient and safe use of fuel: hot air heating is a fully mature heating process, convenient and safety filling and using of diesel, provides convenience for construction.
