Excavator Drum Cutter Description
The Excavator drum cutter is composed of a hydraulic motor, out
body, and one or two drums equipped with some number picks on it.
One drum is a vertical hydraulic drum cutter, two drums are
horizontal. When the excavator hydraulic system offers hydraulic
power to the drum cutter motor, it would drive the drums to rotate.
Then those picks start to rotate at a high frequency to deal with
demolition work (rock, concrete), milling, tunneling, softening the
frozen ground and etc.

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
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.
