When choosing a down-the-hole (DTH) drilling rig，you need to consider various factors. This article will guide you on how to choose the right down-the-hole (DTH) drill from three important parts: drill bit, drill pipe, and impactor. .
The higher the working pressure of the down-the-hole drilling impactor, the faster the rock drilling speed. Since the drill impactor is designed according to a specific. .
The impact energy of the down-the-hole drilling impactor must ensure the specific energy of the drill bit, so as to effectively break the rock, and at the same time obtain a more. .
Generally, when the impact energy is constant, the higher the impact frequency, the greater the impact power. However, the outer diameter of the impactor is constrained by the diameter of the borehole. The higher the impact frequency, the smaller its impact energy. Therefore, the increase of impact frequency is limited by the specific. [pdf]

When rock drilling, the impactor dives into the hole, and the piston (hammer) in the impactor reciprocates to strike the shank through the gas distribution device (valve) so that the drill bit impacts the rock at the bottom of the hole. The high-speed rotation of the impactor in the hole is. .
A down-the-hole drill, usually called DTH Drilling Rig, is basically a mini jackhammer screwed on the bottom of a drill string. The speedy hammer activity breaks hard stone into little flakes and dust and can be dismissed evident by the air exhaust in the DTH hammer. Considering that the DTH method. [pdf]
