How Much Output Can Be Achieved By Crushing Concrete With Drum Cutter
2022-05-09
The application of drum cutter in engineering is very extensive. It can not only be used in the excavation and excavation of tunnels and roadways, but also in road pavement crushing, open-pit coal mining, wall contour trimming, etc. In the steel industry, construction industry, forestry and other diversified construction fields.
There are many types of rock and soil layers that the drum cutter can dig. For medium and low hardness rocks, such as weathered stone, tuff, etc., considering the density and degree of fragmentation of the rock, the milling efficiency of the drum cutter can reach a maximum of 25~40m³/h. For concrete, if there is no steel bar in it, the drum cutter can easily mill and excavate, and the output can reach 40-50m³/h. If there is a small amount of steel bars and the diameter is less than 30mm, the drum cutter can be installed on the excavator of more than 300 tons, and efficient milling and excavation can also be realized.

The advantages of the drum cutter are low noise and low vibration, which can avoid unfavorable situations such as rock strength reduction, structural loosening and local rupture caused by vibration during construction, thereby avoiding large-scale collapse of the house. Especially in the construction of tunnels, drum cutter can replace very expensive equipment such as tunnel boring machines and shield machines, greatly reducing construction costs.
The drum cutter is very effective in the mining of the following rocks: low hardness rock, weathered rock, high hardness but structurally layered rock, and the milling volume can reach 80-120 tons per hour (depending on the rock's size). In terms of hardness); the drum cutter can replace the excavator construction well, and can protect the environment well.

There are two basic types of drum cutters: transverse drum cutter and axial drum cutter. Two basic structures: gearbox transmission and hydraulic motor direct output. The transverse drum cutter is a horizontal direct output structure, and the motor is directly installed in the rotating part, which reduces the gear transmission link and does not require any modification. It has the characteristics of high strength and simple installation. The axial drum cutter (tunnelling drille) is a horizontal proportional gear output, and the motor is installed at the rear and is driven by gears. It has the characteristics of not easy to leak oil and easy maintenance.
