XWV90 Vertical Drum Cutter

The XW milling and excavating machine can be installed on any type of hydraulic excavator, efficiently replacing general configurations such as digging buckets, crushing hammers, and hydraulic shears. It is applied in multiple fields such as open-pit coal mines, tunnel excavation and contour correction, channel groove milling, asphalt concrete pavement milling, rock permafrost milling, and tree root milling. The milling and excavating machine provides a new construction method for tunnel excavation.

Features of XW milling and excavation machine:

1. Wide range of milling and excavation;

2. Low vibration and low noise;

3. Accurately control construction;

4. The material excavated by milling has a small and uniform particle size, which can be directly used as backfill material;

5. Good safety;

6. Simple structure and convenient use.

The drilling and blasting method is not divided into TBM method, milling and digging method and double-arm boring machine excavation method, etc. Milling and digging method is the hydraulic lateral milling and digging machine assembled on the hydraulic excavator, used in tunnel excavation and renovation of the wheel corridor, cave, cross hole excavation, etc., especially suitable for the area not suitable for engineering blasting construction, at the same time, the tunnel structure specifications and industrial equipment high efficiency and cost analysis report.

In the tunnel construction of urban metro section, the mine lateral milling and dredging machine can meet the drilling and excavation of hard surrounding rock with different compressive strength. Compared with the drilling and blasting method, the vibration of surrounding rock is smaller, the safety factor is higher, the control accuracy of the excavation wheel corridor is higher, and the overcut and undercut can be controlled reasonably, especially in the area where there are not only structures but also extremely strict control of the foundation settlement. It is suitable for underground tunnel excavation in the no-explosion zone. However, the application of milling and dredging machine is limited for the geological structure with relatively developed fissure water in surrounding rock, so the application effect is not ideal in the hard siltstone tunnel in this area.
