Low Air Pressure DTH Hammer
- Length: 800-908mm
- External Diameter:80-137mm
- Hole Range:85-178mm
- Working Pressure:0.5-0.7Mpa
product Introduction
Low air pressure DTH hammer is a kind of impactor with plate valve, single piston and central exhaust structure, which is driven by compressed air. Little amount of high pressure water can be added to the compressed air to prevent dust pollution.
Features
- 1Large single impact energy, low energy consumption for rock drilling.
- 2Approximate weight ratio of piston and drill bit and long efficient acting time are benefit to increase rock drilling efficiency and prolong the drilling tool service life.
- 3Good effect of central exhaust and slag discharge, reducing the repeated crushing of rock.
- 4Equip with check-valve assembly, making drilling in water possible.
Application
Low air pressure DTH hammer is ideal perforating equipment in the industries of energy, transportation, metallurgy, building materials, etc.
