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 milling head of the mining hydraulic milling and digging machine is divided into two milling and digging drums on the left and right, each milling and digging drum has 24 (German milling and digging machine) or 36 (British milling and digging machine) cutting teeth symmetrical layout with double helix structure line method. Each screw is electrically welded with helical gear, which is used to strengthen the welding of milling and digging tooth base and milling hub, and at the same time is conducive to crushing the milling surface of rock stratum. The cutting order of hydraulic milling and digging machine in mine is sequence type and frame-line type mixing method, while the cutting order of British milling and digging machine is alternating type.

In the design of the cutting head, the effective selection of the main parameters and the layout of the cutting gear can make the best cutting block, the least cutting energy consumption, the least load fluctuation of the cutting head, the more stable in the work of the roadheader. There are many main parameters that harm the structure type and production efficiency of milling head, but the radial spacing of cutter tips has great harm to the bearing capacity difference of cutter teeth.
