SD 8 Down The Hole Hammer

SD 8A DTH Hammer SD 8 Down The Hole Hammer for Stone Quarrying Drilling

Down The Hole Hammer, i.e. Pneumatic impactor, also known as pneumatic impactor, pneumatic dive hammer. To the compressed air as the power medium, the use of compressed air energy to produce continuous impact load hole at the end of power equipment.

Compressed air at the same time can also doubles as a wash hole medium. Pneumatic impactor has high wind pressure and low wind pressure, valve type and no valve type of points. Usually the pneumatic impactor directly connected with the carbide rod tooth drill to impact the way rock, low-speed rotation is not coring the full drilling. Mainly used in hydrological wells drilling, non core geological drilling, geological disaster prevention and control projects and mine drilling and other fields. Suitable for use in gravel and hard rock formations, specially configured drill bits can also be used in soft soil. Mechanical drilling speed is generally much higher than the hydraulic impactor drilling, but need to be equipped with a larger capacity of the air compressor, fuel consumption, noise, dust pollution. Drilling depth by the groundwater level, the greater the impact of water.

Description:

It is a kind of high air pressure DTH Hammer without footvalve, our newest design. It is also one of the most advanced DTH Hammers in the world.


Main Advantages:

1. Out of the trouble of foot valve fracture and expansion and contraction.

2. Lower energy consumption and higher impact frequency. The drilling speed is 15%-30% higher than the one with foot valve.

3. Simple structure, reliable parts, long life, easy and cheap maintenance.

4. Lower air and oil consumption. The oil consumption is about 10% lower than the one with foot valve.
