DOWN THE HOLE DRILLING HAMMERS
DTH hammer is used for drilling holes through a wide range of rock
types, the variety of which continues to extend well beyond the
original conception of early blast hole drilling.
Down-the-Hole refers to where the hammer action occurs when
compared to drifter hammers, which hammer on top of the drill
string. The DTH hammer piston always makes direct contact with the
drill bit and there is generally no loss of transmitted energy as
the hammer drills deeper, as is the case with drifter (top hammer)
rigs.
Roschen offers a wide range of DTH hammers suitable for a variety
of drilling operations. Our Down the Hole hammers provide the most
versatile and cost effective rock drilling method.

Description:
High air pressure DTH Hammer without footvalve, whichs has been one
of the most advanced DTH Hammers in the world is our own design.
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.
