Working Principle
The Kaishan K8 DTH hammer operates on the principle of down-the-hole drilling, where the hammer is positioned directly above the drill bit at the bottom of the hole. Compressed air is supplied through the drill pipe to the hammer, driving a piston that strikes the bit with high impact energy. The bit then crushes the rock, and the air flow flushes cuttings out of the hole. This mechanism allows for efficient energy transfer and fast penetration, especially in hard rock formations. The hammer's internal design ensures optimal air distribution and minimal energy loss, resulting in high drilling efficiency and reduced fuel consumption.
