Milling boring machine known as milling excavator. Hydraulic milling and digging machine sales manufacturers share resources is basically planned in the ballast scraper machine, called milling and digging machine. Milling and digging machine provides a new engineering construction method for tunneling, which is mainly applied in several fields, such as excavation of underground foundation pit, tunnel excavation and wheel corridor adjustment, pipe trench milling and groove milling, ground grinding equipment of asphalt mixture, grinding excavation of rock frozen powder, excavation of pilot canal foundation pit, excavation of sewage pipeline foundation pit, etc. Milling machines and excavators can be found in many places in China. Its large shopping malls have great harm to tunnel excavation.
First, the application of milling and digging machine is very rich; Mine lateral milling and dredging machine is suitable for the hard structure of the operation of the natural environment, is a special operation machinery equipment. Its structure determines that the milling excavator can excavate and equipment raw materials above or below the shutdown surface for three-dimensional operations. Therefore, the application range of iron excavator is very strong, which expands the wastage of a vast large shopping mall for milling and digging machine. Together, the function of the milling machine is intact, in the assembly of a variety of accessories, can be removed, broken, flat, accurate lifting and other practical operations, for a common machine.
Second, in recent years, the manufacturing level of milling machines and excavators in China has been greatly improved, together with the active sales strategy and price war of China's famous brands further reduced the purchase cost of milling and digging machines, coupled with the steady growth of some companies, the continuous investment of technical research and development and the continuous maturity of milling machine technology, gradually promoted the improvement of the volume of milling machine market.
Work category of rock and soil longitudinal milling and digging machine
1. The replacement of explosive engineering construction by cutting and excavators prevents the reduction of compressive strength, structural loosening and partial rupture of rocks caused by explosion vibration, which is beneficial to the maintenance of the original self-reliance of rocks and is not easy to lead to large-scale loss.
2. In the process of tunnel construction, it can replace tunnel boring machine, boring machine and other expensive mechanical equipment, greatly reducing the construction cost; The milling machine is usually reasonable in the following rock mining operations:
Low strength rock; Weathered rock; High toughness but layered rock grinding equipment can achieve 80-120 tons per hour (depending on the strength of the rock). Milling machines and excavators can effectively replace the engineering construction of excavators and effectively maintain the natural environment.
3. Soft application, small and medium-sized milling and digging machine, according to the natural environment of operation, can replace different milling head, pipe cutting and excavation wheel, rock saw, easy and convenient replacement. It is widely used in a variety of engineering construction scope, especially in the excavation of coal roadway and rock roadway whose rock compressive strength is less than F5.
