Working Principle

The Kaishan KG726HIII operates on the Down-The-Hole (DTH) hammer drilling principle, where a pneumatic hammer is integrated into the drill string just above the drill bit. High-pressure air is supplied through the drill pipe to the hammer, driving the piston to strike the bit with high frequency. This impact energy fractures the rock, while the rotation of the drill string ensures even wear and round holes. The air also serves to flush cuttings out of the hole, keeping the bit clean and efficient. The rig's hydraulic system controls the feed force, rotation speed, and tramming, allowing precise adjustment to rock conditions. The powerful diesel engine drives the hydraulic pumps and air compressor, ensuring reliable operation. The automatic rod handling system adds or removes rods quickly, minimizing downtime. This combination of impact, rotation, and flushing results in fast penetration rates and straight, accurate blast holes, making the KG726HIII ideal for surface mining and quarrying.
