4. How to choose the suitable Pneumatic DTH hammer?
Hole Size:
Selecting the one whose outside diameter is closest to the hole diameter will be in your best interest. As a result, there will be less hole collapse and easier hole cleaning.
Air Consumption:
It is important to take into account the compressed air usage when using the pneumatic DTH hammer. Generally speaking, peak performance necessitates lower pressure and more compressed gas consumption as the hammer size increases. Please refer to the attachment to ensure that each hammer is used with the appropriate amount of pressure and compressed air.
Drill rig Capacity:
The drilling rig must supply more torque and promoting force to accommodate the larger bit and hammer, but it must not go above the drill's maximum load. As for the other questions about drill ability, please consult your sales representative.
5. Is top hammer drilling vs down-the-hole drilling?
The primary difference between the top hammer and down-the-hole drilling methods is where the hammer is attached. The hammer in the industrial equipment makes contact with the bit during the down-the-hole drilling method. The top hammer drilling method's activity is concentrated at the very top of the drill string.
