The Palion Drum Milling Machine is produced with the world's leading cutting-edge technology and can be installed on any type of hydraulic machinery and excavator. It is used in many fields such as underground mining, open-pit coal mining, tunnel excavation and contour correction, channel trench milling, asphalt concrete pavement milling, rock frozen soil milling, tree root milling, municipal housing construction, etc. The Drum Milling Machine provides a new construction method for tunnel excavation and coal mining.
There are two basic types of Palion Drum Milling Machines: horizontal Drum Milling Machines and vertical Drum Milling Machines.
Application fields of Pailien milling machine:
Pailien milling machine can be widely used in tunnel, ditch, municipal pipeline excavation; high-speed rail high-speed grooving: highway pavement crushing, mining rock frozen soil excavation; open-pit coal mine excavation, no explosive blasting, low vibration, surface new and steel industry, forestry and other construction fields: Pailien milling machine is used in tunnel excavation. In most cases, the milling machine is only used for tunnel contour excavation, but in suitable strata such as medium and low hardness rock strata and frozen soil strata, the milling machine can be directly used for tunnel excavation, especially in the process of breaking and excavation, the disturbance to the stratum is low and the safety is high. In the broken rock strata and old loess, the excavation volume reaches 30--60m3/h.
Pailien milling machine is particularly suitable for areas where blasting construction is not suitable; the milling machine is simple to operate, highly controllable, and the excavation contour line is clear and accurate, which can easily solve the problems of under-excavation and trimming in the tunnel, inner surface grooving and excavation of side ditches.
Excavation: On-site excavation is generally carried out in two steps, namely the two-step step method. Since all equipment needs to be stored on the steps, the upper and lower steps are 800-1100m apart. Step-by-step excavation support: After excavation, steel mesh, steel grid + mud spraying are used to support the tunnel. In soft rock,
