Application fields
One , engineering fields: earthwork projects, demolition projects, road and bridge projects, tunnel excavation projects, (non) excavation projects, water conservancy projects, etc.
2. Mining field: stone mining (marble, granite, sandstone, limestone, etc.), metal mining, coal mining, sand and gravel mining, etc.
Low energy consumption, the whole set of machine energy, drilling the same rock blasthole is only the wind energy consumption/
The impact energy is joules and the impact frequency is small. The frequency is high, that is, the gun head can achieve 10 impacts per minute, and the rotation can drill powerfully with maximum force. When the drilling hardness is Platts granite blasthole, the drilling speed per minute can reach above, that is, if it works continuously, it can reach about diamond meters per hour.
The rock support fully ensures the verticality of the drilling and the parallelism of the vertical blasthole.
Easy to install and transport, suitable for field operations.
The noise of the pressure rock drill is lower than that of the pneumatic rock drill, and the use of the frame for drilling also greatly improves the working environment of workers.
Long service life, the life of the key component impact piston is more than twice that of the pneumatic one.
The pressure rock drill has a large torque, which reduces fiber jamming. The impact stress wave is close to a rectangular wave, which increases the service life of the drill tool.
The price is low, only one-third of similar foreign products.
