Rotary Drum Cutter

Rotary drum cutter, also known as a rock grinder, rock drum cutter, or hydraulic milling machine, is a specialized excavator attachment. It features a rotating drum equipped with multiple cutting teeth or picks. As the drum rotates, the teeth engage with the material, breaking it down into smaller pieces for easy removal. This method of excavation is highly effective, offering precise control and minimal disturbance to the surrounding environment. It is powered by the excavator’s hydraulic system and can efficiently grind, mill, and cut through a wide range of materials.

Applications of Excavator Drum Cutter

1. Trenching for Pipelines and Cables
   Rotary drum cutters excel at creating narrow, deep trenches for the installation of pipelines, cables, and other utilities, ensuring minimal disruption to the surrounding area.
2. Foundation Excavation
   For building foundations, it provides the precision needed to excavate to exact specifications, ensuring a stable and level base.
3. Tunneling and Mining
   In tunneling and mining operations, hydraulic drum cutter is used to bore through rock and soil, facilitating the creation of tunnels and shafts with minimal environmental impact.
4. Demolition and Site Preparation
   Rotary drum cutters can also be employed in demolition projects to break down concrete and other hard materials, as well as in site preparation tasks such as clearing land for construction.
