Product Details

Description

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 for getting a better performance .

Performance

The performance of low air pressure DTH hammer
1.Large single impact energy, low energy consumption for rock drilling.
2.Approximate 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.
3.Good effect of central exhaust and slag discharge, reducing the repeated crushing of rock.
4.Equip with check-valve assembly, making drilling in water possible.

Applications

Low air pressure DTH hammers are used toUnderground Mining, Water well, Mining, Quarry etc.
