Rock Grinder Attachment For Excavator 20-40T Excavator Drum Cutter
Excavator Horizontal Drum Cutter
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 offer 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
