1.The reverse circulation DTH hammer provides large impact of torque and high efficiency of energy transfer while ensuring saving energy consumption.
2.It delivers high drilling efficiency due to strong capability of removing rock dust and flakes.
3.Compressed air and reverse-flow fluid medium are all transported in the sealed double-wall drilling tool, thus avoiding direct ccontact with the borehole wall and maintaining stability of the wall. The reverse circulation hammer shows unique effect to complex and leakage formations.
4.Rock sample will be carried by the fluid medium and directly go back to the ground through the center hole of the drilling tool. It will not touch the wall of borehole, ensuring high quality of ore sample with no pollution.
