Best Medium Air Pressure DTH Hammer on sales introduce the human-rock mechanism of the DTH hammer

2023/04/07

Best Medium Air Pressure DTH Hammer on sales tells you that the pneumatic down-the-hole hammer is powered by high-flow high-pressure air, which drives the piston of the impactor to reciprocate at high frequency, and continuously transmits the kinetic energy generated by this movement to the drill bit. Under the action of impact energy, the rock at the bottom of the hole is continuously impacted.

Best Medium Air Pressure DTH Hammer on salesBest Medium Air Pressure DTH Hammer on sales tells you that under the stress concentration of the spherical indenter, the rock produces elastic deformation, cracks, crack propagation, brittle cracking, and finally forms a broken pit. There are rock ridges between the crushing pits, and the surroundings of the rock ridges are hollow, which is easy to break next time.
unloading. Best Medium Air Pressure DTH Hammer on sales tells you that the exhaust hole in the center of the down-the-hole hammer, the large-flow airflow discharged, blows the broken rock debris through the exhaust duct, and falls into the debris on the top of the down-the-hole hammer. After single-bucket drilling, lift the main roll to lift the down-the-hole hammer out of the hole, lift the power head to lift the left and right steel wire ropes, lift the cuttings barrel in a balanced manner, turn the power head left and right, and the cuttings will fall.
Holes are formed in stages. Best Medium Air Pressure DTH Hammer on sales will tell you the wind limit that is most affected by the wind and can be supported. If the hole diameter is larger than 1.2m, the cluster DTH hammer split fire hole (hole reaming) technology can be used to effectively reduce resources and costs. First use the small-diameter cluster DTH hammer to break the rock to form a hole, and then use the large-diameter cluster DTH hammer to expand the hole. A guide ring device is installed at the bottom of the hole hammer in the large-diameter water collection room. The guide ring is consistent with the diameter of the first hole. The guide ring is inserted into the hollow hole to play a positioning and guiding role.

Through the above introduction and analysis of Best Medium Air Pressure DTH Hammer on sales introduce the human-rock mechanism of the DTH hammer, hope it helps you.
