D85A Dth Hammer
COP 84 DHD 380 Down The Hole Hammer
D85A DTH Hammer COP 84 DHD 380 Down The Hole Hammer For Gravel and
Hard Rock Formations
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.

Product 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.
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.
