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 key construction function of the excavation link of the intermediate air shaft is low, and it is in the mud rock layer of China's regolith. When the tensile strength of the rock stratum is 15.3Mpa, the working efficiency of the tunnel lateral milling and digging machine is about 3-5m3m, which is less than the 19m effect of the crushing hammer of the excavator. In the whole process of the construction of the section, it is based on the geological structure standard on the construction site and the space regulations of the machine and equipment working room. Adjust the tunnel excavation plan; In the tunnel, there is also a state of reduced function, which is lower than the construction effect of the crushing hammer of the excavator. At the same time, the siltstone fissure water in the tunnel is relatively growing and developing. Sandstone leakage is relatively large, rock lateral milling and digging machine in the milling and digging process will be broken siltstone, more smoke occurs in the whole construction process, tunnel working conditions are poor, at the same time, milling and digging after small pressure test siltstone particles produced sand slurry is very easy to stick to the milling and digging head, harm the middle and late construction work function: In the whole process of construction, it is necessary to remove the milling and digging head anytime and anywhere, but after cleaning, the siltstone excavated on the spot will produce sand slurry. Further harm the civilized behavior of the cave construction and the transportation of residual soil.
