Product Description

SD10A DTH Hammer SD10 Down The Hole Hammer For Hydrology and water well drilling


Pneumatic impactor 

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. 

Subject: Drilling Engineering 


Glossary: Pneumatic Impactor, Down The Hole Hammer 


Pneumatic percussion hammer, pneumatic down-tme-hole hammer 


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, no 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.


SD10A DTH Hammer (SD10) 

Basic Info
Model NO.: SD10
Mining Object: Mining
Origin: Germany,China
Type: Drilling Machine
Trademark: ROSCHEN
HS Code: 84123100





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.


It has the following 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.
