Product Description
DTH Drilling Hammer DHD Series Hammer Without foot valve For Mining
The Characteristics Of High Air Pressure DTH Hammers Without foot valve:
It is a kind of high air pressure DTH Hammer without foot valve, our newest design. It is also one of the most advanced DTH Hammers in the world.
Advantages as follows:
1. Out of the trouble of foot valve fracture and expansion and contraction.
2. lower energy consumption and higher impact frequency.
Advantages as follows:
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.
