Rotary Drum Cutter
The excavator rotary drum cutter is an attachment that can be quickly installed on the front end of the excavator. It uses the hydraulic power of the excavator to drive the rotating drum to perform milling operations, greatly expanding the functions of the excavator. The excavator milling head has the advantages of flexible operation, strong mobility, and a wide range of applications. It can perform efficient operations under various complex working conditions. Whether it is the demolition of concrete structures in urban infrastructure construction, rock crushing in mining, or contour finishing in tunnel engineering, the excavator drum cutter can demonstrate excellent performance.

Power drive: A rotary drum milling machine is usually powered by a hydraulic motor or an electric motor. Hydraulic systems are the more common choice because they provide high torque and adjustable speed, which is essential for dealing with materials of different hardness.
Power transmission: The power of the electric or hydraulic motor is transmitted to the rotating drum through a gearbox, belt, or other transmission mechanism. The gearbox is usually used to reduce the speed of the motor and increase the torque to meet the needs of the milling operation.
Drum rotation: The drum that receives the power starts to rotate at high speed. The drum is usually made of high-strength steel, and many knives or cutter heads (also called teeth or picks) are welded or installed on its surface.
Material cutting/milling: When the high-speed rotating drum contacts the material to be removed (such as concrete, rock, asphalt, etc.), the knives or cutter heads on the drum will peel or crush the material bit by bit by cutting or milling. Each cutter head will exert impact and shear force on the material during rotation.
Cutter head design: The material of the cutter head is usually cemented carbide, which has high hardness and wear resistance and can effectively cut various hard materials. The shape and arrangement of the cutter head will be optimized according to different application scenarios and materials to be processed to improve cutting efficiency and effect.
Material discharge: The cut material fragments will be discharged as the drum rotates. Some milling machines are also equipped with a water spray system for dust reduction and cooling of the cutter head, which also helps to flush away the cut debris.
Building demolition and renovation: In urban renewal projects, it is used for precise demolition of concrete structures, brick walls, etc. Compared with blasting, it has less noise and dust pollution and higher safety.
Road and bridge construction: It is used for asphalt pavement milling, bridge deck cleaning, bridge pier reinforcement, etc. to improve construction efficiency and quality.
Tunnel and mining engineering: It is used for excavation of rocks and ores, trimming of tunnel contours, tunneling, etc., and can operate in small spaces or special geological conditions.
Water conservancy engineering: It is used for river dredging, dam maintenance, demolition of underwater structures, etc.
Landscape construction: It is used for rock shaping, earthwork excavation, ditch excavation, etc. to achieve refined operations.
Special applications: For example, it is used for slag cleaning in steel mills and dock maintenance in ports.
Key Factors for Choosing the Right Rotary Drum Milling Machine:
Type and hardness of the material to be processed: Different materials require different types of cutter heads and drum designs. For example, for hard rock, you need to choose a milling head with a highly wear-resistant cutter head.
Required cutting depth and width: Choose the appropriate drum size and cutter head arrangement according to the specific construction needs.
Excavator model and hydraulic parameters: If you choose an excavator milling head, you need to make sure it matches the excavator model and hydraulic system to ensure optimal working performance.
Constraints of the construction environment: For example, in a small space or an area with noise restrictions, you need to choose a small and low-noise device.
Durability and maintenance cost of the equipment: Choosing equipment with reliable quality and easy maintenance can reduce long-term operating costs.
Easy to replace the cutter head: Frequent replacement of the cutter head is normal maintenance work, and choosing equipment that is easy to replace can save time and labor costs.
Supplier reputation and after-sales service: Choosing an experienced and reputable supplier can get better product quality and after-sales support, such as a professional manufacturer: YG Machinery.
