Working Principle

The Kaishan KG920D operates on the down-the-hole (DTH) drilling principle, where a pneumatic hammer is located at the bottom of the drill string, directly above the drill bit. High-pressure air is supplied through the drill pipe to drive the hammer piston, which strikes the bit with high frequency and impact energy. The rotation of the drill string is provided by a hydraulic rotary head, ensuring the bit indexes between blows. The cuttings are flushed out of the hole by the exhaust air, which also helps to cool the bit. This method allows for efficient drilling in hard rock formations with minimal deviation. The KG920D's hydraulic system controls the feed force and rotation speed to optimize penetration rates, while the dust collection system captures airborne particles for a safer working environment. The entire process is managed from the operator cabin, providing precise control and real-time monitoring.
