The excavator milling machine utilizes the hydraulic system of the excavator to mill rocks, frozen soil, coal mines, concrete, and other materials. It serves as an efficient replacement for common attachments such as buckets, breakers, and hydraulic shears. This versatile attachment is widely used in various fields, including opencast coal mines, tunnel excavation and contour correction, trench and channel excavation, asphalt concrete pavement milling, rock and frozen soil excavation, and tree root milling.
l Applicable to a variety of materials
l Suitable for working in sensitive areas
l Able to achieve fine construction
l Milled materials can be used directly as backfill
l Replace manual dangerous operations and reduce safety risks.
l Can be installed on various hydraulic excavators and is easy to operate.
The milling digger is widely used in sectors such as opencast coal mining, tunnel excavation and contour correction, channel and trench excavation, asphalt concrete pavement milling, rock and frozen soil milling, tree root milling, and more. It provides a novel construction method for tunnel excavation and can also handle tasks like breaking, trenching, milling, excavation, and wood sawing, further enriching the functionality of excavators.
