HD525 DTH hammer

24 inch DTH hammer is kind of pneumatic rock drilling tools, the difference from others is during drilling process hammer always stay in the bottom of the hole, impact the rock by bit from hammer directly. High pressure air enter into the hammer through drill pipe, then run out from drill bits, exhaust air used to blow up cuttings from the bottom of hole. The rotating power acting on DTH hammer comes from rotaion motor on the drill rig, the pull force comes from feeding device and transfer the energy to hammer through drill pipe.

HD525 DTH hammer working principle

Drilling bit press against the rock.
High pressure air burst through the check valve from drill pipe, enter the front cavity of hammer.
The increase of the front cavity volume push the piston to move upward.
When the piston moves up to a certain extent, the front cavity deflates and the compressed air enter into the back cavity. Piston keep moving upward because of inertia.
When the piston to a certain extent, due to the compression of the back cavity and the increase of air pressure, the piston starts to impact downward which forming an impact strok. Moves up circles as the above process to achieve impact and complete rock drilling.
