D&G Machinery provides customers with full support in terms of equipment and constraction application in order to offer customers with comprehensive solution to the project, as well as to provide equipment modification service upon their request.


Modified asphalt equipment


Main features:

1. Integrated modular design and easy to move

2. With the heater and high-efficiency mixer, the heating and mixing process can implement at the same time.

3. The shear machine is integrated with cutting and grinding function. The key components as like stators and rotors as well as blades are made of high abrasive resistance and corrosion resistance material. The whole machine are assembled with high precision to ensure stab running and long term service. 


Barreled Asphalt Melter


Asphalt Melter is used for heating and dropping barreled asphalt, which heated by hot oil and burner. The hot oilheater can be separated with or combined into decanter.

Model                                        DLT-10

Capacity                                    10 t/h

Volume of bitumen pool            15m³    

Number of barrel                       28   or    32 barrels

Barrel orbit quantity                   2 lines

Outline dimension L*W*H  ≈11.9m×2.2m×2.55m

Heating mode                           Separated or combined Hot oil heater withburner

 

Decanter use hydraulic propulsion structure, main advantages:

1.      No need underground foundation, hardened ground will be ok.

2.      No need laying tray for barrels.

3.      Using hoisting device to move barrels, rather than manual work.

4.      Using turnover device to pull barrels, rather than manual work, without leakage.

5.      Using reinforced & sliding tracks to avoid distortion.

6.      Using spring doors to reduce heat loss.

7.      Low labor intensity, safe and reliable.

8.      Hot oil heater equipped with burner can be separated with or combined into decanter.


Pelletized cellulose fiber dosing and adding system


This equipment adopts the advanced CB4 weighing display and Siemens PLC, to add the anti-rutting pellet as well as xylem fiber. This devise will start after get the signal from the controlling system, auto weighing, dosing and adding for the pellet, and integrated with automatic protection and alarm for the working failure. The dosing tolerance is 1.2 percent, with function of internet connection, printing, disc saving. This system has the advantages of working stable, dosing accurate and easy to operating.

DG Warm Mix Foaming Device


1 .introduction

   Foaming bitumen system is consisted of  foaming unite, water dosing and supply unit,water replenishing unit, and controlling system. It has lots of the advantages compare with the normal mix bitumen. Foaming bitumen can be used under thetemperature 50-60°that much lower than the hot mix bitumen, Which can reduce the projectcost and pollution emission. Feed the foaming medium (water or vapour) into the high temperature liquid bitumen, the medium and the bitumen combine to the mist. The bitumen adhesion will be less and the volume will expand rapidly. This expansion is purely physical processed, the chemical property of the bitumen do not change.

2. Advantages

   Greatly reduce the hot mix temperature(30-50°)

   Cost saving-10%-30% power saving

   Less discharge
