Working Principle
The Kaishan K4 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 fed through the drill pipe to the hammer, driving a piston in a reciprocating motion. The piston strikes the bit with high impact energy, fracturing the rock. Simultaneously, the exhaust air flushes the cuttings out of the hole through the annular space between the drill pipe and the hole wall. This design minimizes energy loss and allows for efficient drilling in hard rock. The hammer's valving system controls the air flow to ensure optimal impact frequency and energy transfer. The K4 is engineered to deliver a balance of power and air efficiency, making it a reliable choice for demanding drilling operations.
