8inch DTH Rock Drilling Hammers for Blasting Drilling Cop84, DHD380, SD8, Ql80

 

Product Description:

In DTH drilling, the drill string rotates while the drilling hammer continuously strikes down into the rock. Inside the hammer, a piston powered by compressed air gives the drill bit its striking power. This combined with the rotational movement means the rock is crushed in a very efficient manner.

In very hard rock (and especially fractured hard rock), down-the-hole (DTH) drilling can be employed. In this case the hammer, applying repeated percussive pressure, is located just behind the drill bit inside the hole, unlike the open percussion drilling, where the hammer is on top of the drilling string.

 

Product Advantages:

1.In this design of the DTH hammer, the user can directly connect with the drill pipe without changing the diameter of the joint, thereby reducing the user's production costs.

2.The DTH hammer select the best raw materials and the most advanced processing technology, more stable performance and longer service life.

3.The internal structure of the DTH hammer is the simplest, most reliable, convenient to disassemble, less trouble, and easy to maintain. Since all components are heat treated, there are fewer failures and easier maintenance.

4.The DTH hammer with valveless air distribution is more reliable.

5.More efficient energy transfer, faster drilling, lower air consumption and lower fuel consumption.

6.Since the top connector is easy to remove, the drive chuck and external cylinder are connected by multiple threads.

7.Please note that the DTH hammer is designed to drill holes in various rock requirements. It is worth noting that when the piston of the DTH hammer is in contact with the drill, it will not lose the transmitted energy as the hammer deepens.
