YAKAI Excavator Drum Cutters Single Head Drum Cutter Rock Grinders
Excavator Drum Cutter Description
The drum cutter is divided into the transverse milling machine and
longitudinal milling machine. It is widely used in the open-pit
coal mine, tunnel tunneling and contour correction, channel groove
milling, asphalt concrete pavement milling, rock frozen soil
milling, root milling, and iron and steel industry, forestry, and
other construction fields.

Features of Excavator Mounted Drum Cutters
- The disturbance to the surrounding rock is reduced, and the rock
strength decline is caused by blasting vibration which is not easy
to cause large-scale deformation and local collapse.
- Long service life, durable milling head bearing structure, and
wear-resistant cutter head.
- Widely Apply, It can cut medium hard and below medium hard rock in
large areas.
- Relatively Low noise, Can be used in multiple operating
environments
Application of Excavator Hydraulic Drum Cutters
Widely used in open-pit mines, coal mines, tunnels, and so on.
Excavation and contour correction, groove milling, and
excavation.Asphalt concrete pavement milling planing, rock
drilling, earth and stone milling planing, frozen soil milling
planing, steel industry, forestry, and other construction fields.
The Hydraulic drum cutter can be supplied with either
scaling/grinding or rock cutting drums. Mainly used for rock or
concrete walls, ditching, removal of soft rock, and frozen soil.
It is widely used in the excavation of tunnels, ditches, and
municipal pipelines. Road fragmentation, mining, rock, and frozen
soil excavation. Open-pit coal mine excavation, surface creation,
steel industry, forestry, and other construction fields.
In most cases, the drum cutter is only used for the excavation of
the tunnel outline, but in the middle and low hardness of the rock
and frozen soil, and other suitable strata, the milling, and
digging machine can be directly used for tunnel tunneling; Suitable
for blasting construction of the lot; It can easily solve the
problems of undercutting and repairing in the tunnel, gouging on
the inner surface and excavation of side ditch.
