Wirtgen cold recycling technology and equipment

First, background

The traditional highway maintenance process has low efficiency, long duration, serious pollution and waste, heightening the shortcomings of pavement repeatedly.

The history of Wirtgen cold regeneration:

1, twentieth Century 70s to Wittgen's invention of the world cold recycling equipment, and successfully applied in engineering practice;

In 1998 2, Wittgen China (Hebei Handan) for the first time in the domestic application of cement cold regeneration;

In 2004 3, for the first time in China Chinese Wirtgen (Jiangsu Wuxi) application of foamed asphalt cold in place;

In 2005 4, for the first time in China Chinese Wirtgen (Shaanxi Xi'an) application of foamed asphalt mixing plant regeneration.

Two, equipment

The whole series of Wirtgen cold recycling equipment including: WR2000, WR240, WR2500S, 2200CR, WR4200, WM1000, KMA220. Now the company has launched a new product: WR2000XL and WR250.

WR2000XL

1, WR2000XL technical parameters:

Working width: 2000mm

Working depth: 0-500mm

Engine power:

315kW

Maximum work weight:

25.2t

2, accurate control of the sprinkler system:

Computer automatic control of spraying system

Flowmeter accurate measurement

Automatic nozzle cleaning

Accurate proportioning design ensures the construction quality

3, the adaptability of complex working conditions

All wheel drive

Hydraulic lifting of 4 legs

Integral frame structure

Special strength can satisfy the needs of highway construction regeneration

5, clutch + belt drive milling bone to ensure optimum power output

Higher transmission efficiency to ensure more useful work, and save investment, create higher efficiency

6. The cutting system pioneered by Wittgen

Quick change of tool head

Rational layout of rotor

High reliability and cost saving

7, the perfect mixing quality at different depths

Mixing space can be adjusted continuously, to ensure the best mixing performance

8, mature technology to ensure homogeneity of recycled materials

Crushing beam for front door

The back door pressure can be adjusted

The regeneration effect ensures that the gradation is adjustable

9. Flexible mobility of different roads

Welt, full wheel steering, convenient operation, and can be widely applied to the edge of the road, wall, the construction of municipal road construction.

10, such as the Henan provincial highway S249 Sanmenxia, Henan S215 Hangzhou S208 Zhejiang Neihuang dart, dart, WR2000XL have a smooth and efficient completion of the construction tasks.

WR250

1. Main technical parameters

Width: 2400mm

Depth: 0-560mm

Engine: CAT C 18 ATAAC

Power: 571kW

Weight: 30000kg

2, have the perfect view and omni-directional camera system

3, high power and self diagnosis system: quick vehicle diagnosis system

4, the working process of automation: at the end of regeneration can automatically feed back

5, Mount Wutai in Shanxi provincial highway S311, WR250 perfect the way to solve the problem.

2200CR

1. Technical parameters:

Width 2200/2500/3800mm
