Product Features:

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. Air compression and reverse-flow fluid medium are all transported in the sealed double-wall drilling tool, thus avoiding direct contact 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.

5. Rock dust and flakes will be cleaned and discharged to a specific position through the center hole for central disposal, which ensured a prevention of dust and pollution, leads to improve working environment and enhance a longer service life of drilling equipment and attendance rate.

6. The reverse circulation DTH hammer comes with simple structure that accounts for its easy maintenance and handy worn parts replacement.

Reverse circulation hammer. In this method, compressed air or air foam fluid is used as the circulating medium. The annular medium between the inner and outer pipes of the double wall drill pipe is sent to the bottom of the hole, and then the inner tube is returned to the ground. The connection mode of the drilling tools used is: air gap double wall drill pipe special joint RC bit or DTH hammer. Among them, the air faucet has two channels, one is the intake channel, the other is the discharge channel. There are two kinds of special joints: guide joint and cross channel joint. The function of guide joint is to recycle the flushing medium in the annular gap between the inner and outer pipes, the annular gap between the guide bit and the hole wall, and return to the central channel along the central hole of the roller bit after passing through the hole bottom. The cross channel joint can make the circulating flushing medium wash the bottom of the hole with local positive circulation first, and then turn into reverse circulation to remove rock cuttings. Both the roller bit and the DTH hammer can be used. This method can realize "three sides integration" continuous drilling while drilling, flushing drilling and sampling, which changes the traditional production process of separating drilling and sampling. Drilling in medium and hard rock strata can greatly improve the drilling efficiency and significantly reduce the cost.

RC hammer Advantages:

(l) High drilling efficiency;

(2) The sampling is timely and the rate of sampling is high, which is helpful to judge the formation accurately;

(3) When drilling in the aquifer, it can avoid the mud blocking the hole wall and maintain the original natural permeability of the formation. Various rock breaking tools such as cemented carbide, diamond, cone and scraper bit can be used for reverse circulation drilling, and it can be used for rotary drilling, percussive drilling, percussive rotary drilling and other rock breaking methods. The washing medium can be clean water , mud or air. It can drill vertical hole, inclined hole or horizontal hole, and can drill all kinds of strata.
