|Hammer Size||Max Hole Diameter||Water Consumption (Nominal)||Power Source – High Pressure Water|
|80NB DTH||145 mm||4.5 ℓ/sec||140 – 180 bar|
|100NB DTH||180 mm||6 ℓ/sec||140 – 180 bar|
|150NB DTH||250 mm||9.5 ℓ/sec||140 – 180 bar|
The purpose is to drill long and accurate holes in hard rock mining conditions. The DTH hammer is used on the HPE Long Hole Drilling Rig as well as the HPE Reef Boring Drilling Rig.
DTH Hammer can operate on normal mine service water unless it is excessively contaminated. Even then the hammer will continue to operate but life of hammer will be affected. Uncomplicated design and with few working parts it is easy to repair on site without applying high level skills.
