Golden/ Blue/ Black QL50 water well drilling hammer for mineral exploration

 

Products Description
 

A down-the-hole drill, usually called DTH is mainly a pneumatic powered rock or ground drill, in which the percussive hammer is located directly behind the drill bit, so the percussion mechanism follows the bit down into the drill hole. The drill pipes transmit the necessary feed force and rotation to the DTH hammer and bit, as well as compressed air for the DTH hammer. Air flushes cuttings up from the bottom of the hole. Drill pipes are added to the top of the drill string as the hole gets deeper. The piston directly strikes the impact surface of the bit, while the hammer casing gives guidance to the drill bit. The fast hammer impact breaks hard rock into small particles, which are blown up by the air exhaust from the DTH hammer.

 
 
Advantage
 
 hammer is ideal for use in hard, stable rock drilling applications and overburden drilling applications that require casing systems. Compared to conventional air-powered DTH hammers or top hammers, water-powered DTH hammers offer a wide range of advantages, including low energy consumption, a cleaner environment, minimal hole deviation, deeper drilling capabilities, a high power output ratio and minimal impact on the surrounding ground.
