DTH Hammer Test Case History:

This trail was run on a new 3 ½” DTH Hammer which was operated above ground against hardwood cribbing. This allowed the frictional heating from the hammer mechanism to be distributed to the steel exterior surface, where it could be measured in ambient air. The ambient temperature was 75 deg. F, the air pressure applied to the hammer was 120 PSI and the air flow was 185 CFM.

The drill was lubed with 6 oz. of rock drill oil and run for 25 minutes continuously with surface temperature taken on the outside of the hammer casing opposite the piston area. After this sequence, the hammer was dismantled, flushed with solvent, cleaned, re‐assembled, and 6 oz. of Jade Lube was added. So, while the start temp for the oil run was ambient, the start temp for the Jade Lube run was 117 deg. F.

The combination of frictional heating and ambient air cooling led to a Temp increase of 23 deg. F for the rock drill oil and a Temp increase of 9 deg. F for the Jade Lube.  More importantly, from a production standpoint, the blows‐per‐minute went up by about 24% with the Jade Lube over the rock drill oil.

Further testing will reveal differences in internal wear, extended drill life, and increased performance due to the drilling rate improvements as shown by this trial.
