Working Principle

The Kaishan KG590 operates on the principle of down-the-hole (DTH) drilling, where a pneumatic hammer is placed directly behind the drill bit. High-pressure air is supplied through the drill string to drive the hammer's piston, which strikes the bit with high-frequency impacts. Simultaneously, the rotary head turns the drill string, indexing the bit for efficient rock breakage. The feed system applies optimal thrust to keep the bit in contact with the rock, while the flushing air removes cuttings from the hole. The rig's hydraulic system controls rotation speed, feed force, and percussion pressure to match rock conditions. A dust collector captures airborne particles at the collar, ensuring a clean and safe working environment. This combination of impact and rotation delivers fast penetration rates and straight, accurate holes in medium to hard rock formations.
