1. Brief Introduction:

CHTCAD0860 automatic asphalt distributor is researched and developed by our company on the basis of many years of construction and equipment design experience combined with the present road conditions. It is one of the series of asphalt distributing machinery which is easy-operated, economical and practical. It is professional construction equipment specialized in spraying emulsified asphalt, cutback asphalt, hot asphalt, hot modified asphalt and various binder.图片3

On the basis of introduced advanced technologies both domestic and abroad, this distributor add some humanized designs that ensure technical content of construction quality and improve construction conditions and environment. Heat oil pipe is equipped in asphalt pipelines. Heat oil internal heating method guarantees liquid running smooth and prevents asphalt from coke burning. In the process of manual spray, the rotation indicator reads asphalt pump rotation speed. The operator could calculate the corresponding vehicle speed and asphalt rotation speed to different spray volume according to our specified formula, so as to guarantee uniform spray volume. In the process of automatic spray, the operator just set spray volume in the console and start velocity meter, and then the automatic control system could regulate asphalt pump rotation speed according to the vehicle speed, so as to guarantee precise and even spray. Its reasonable designs guarantee the asphalt spray uniformity. This product gets through the strict detection of our operators and enjoys stable and reliable construction performance, and is known as ideal economical road maintenance equipment.

It could be used to deal with upper and lower seal layer, prime layer, asphalt surfacing, asphalt penetration surface, fog seal layer and so on. It also could be used to transport liquid asphalt and other heavy oil.

2. Operation principle:
The operating principle of asphalt distributor is to pump the hot asphalt from asphalt storage pool into asphalt tank through asphalt pump, or add asphalt from the mouth of tank ; Transport it to construction site and heat the asphalt up to working temperature by heating system; Open asphalt pump and spraying valve by operating electrical apparatus control system; According to three overlapping spraying effect to spray the hot asphalt on pavement on the basis of measured distributing amount and pressure. The residual asphalt in pipeline will be transported into asphalt tank after finishing the work.

Asphalt tank

asphalt tank capacity8000L,safe and stable, fast heating speed

It has washboard in the tankwhich can protect from hidden danger.

asbestos insulation layer with thickness of 100mm preserves heat of heated asphalt. Good anticorrosion and durable insulation layer maintain temperature drop by no more than 12℃/8h

Stainless steel frosted board out of the insulation layer is elegant and easy to clean.

Vent are on the tank to keep the ordinary pressure.

It can self-priming and discharge, which can add or discharge the asphalt automatically, increase the efficiency


           Spray System


It adopts Viking asphalt pumpwhich has good pumping capacity large discharge capacitycan do a better performance of asphalt circulation and spraying.

Asphalt Pipeline can realize the HTF whole coverageguarantee the smooth circulation of asphalt in the pipeline.

Special folding Spray Bar are used, proper asphalt circulation and precise nozzle design ensure the accuracy and uniformity distributing precision

It can spray all kinds of asphalt, especially hot (modified) asphalt, diluted asphalt, emulsified asphalt

Spray volume0.2-3kg/m248 nozzles in all. Each has the space of 125mm

Each nozzle can be controlled by computer. Precise spraying and aren’t influenced by speed.

Computer control the whole process of sprayingit can change the spraying width any time to meet the need of different pavement.


         Heating System

Italy RIELLO diesel burner is applied. The Calorific value20×104kcal/h

U-shape heating tube make the system heat fast.

The HTF coil are parallel double loop, make the heat speed fast.

The HTF make the asphalt cover all the pipe, which can realize no-clean.

The upper and lower limits can be set, which are more safe and reliable.


        Air circuit system

Plenty air source directly from the chassis guarantees the good performance of asphalt spray, spray bar lift and swing, air control angle seated valve and water system.

· Long-life service solenoid directional valve and elements are used

Different air circuit Pressure regulating valve and ball valves controlsensure the main vehicle air circuit and the different circuits without interference.


      Water circuit system

The water nozzle are installed on the upper part of each tire, which can effectively prevent asphalt adhesion on the tires during the construction process, avoid tire skidding on the mountain road and reduce tire temperature of long distance travel in summer.

The main vehicle air circuit give the pressure to the water tank, simple and convenient.
