Drum Cutters Applicable to The Mining of Open-pit Coal Mines The Repair and Excavation of Tunnel Rocks and Concrete

Advantage

1.Wide range of Drum Cutter: different types of Drum Cutters can adapt to stratawith different hardness, and concrete without steel bars or with a small amountof steel bars can also be milled.

2.Reduce vibration and protect the environment: it can replace blasting construction, has low vibration and noise, and can better protect the environment.

3.Accurate control of the excavation surface: it can better solve the problems ofover-excavation and under-excavation, accurately trim the excavation contourand help reduce costs.

4.Good safety: the use of Drum Cutters in soft rock or broken rock formations canreplace manual excavation, so that construction personnel can leave the work.ing face and reduce the danger of falling blocks and collapses encountered byconstruction personnel in front of them during the excavation process , toimprove the safety of tunnel construction.

5.Simple structure, easy to use, and relatively low price: it can be installed on anyexisting excavator without special supporting equipment. Compared withtunnels, shields and other machinery, the equipment is cheap.
