DTH hammer and drill bit
Automatic rod changer (optional)

Working Principle

The Kaishan KL511 operates on the principle of DTH (Down-The-Hole) drilling, where a pneumatic hammer located at the bottom of the drill string directly impacts the rock. High-pressure air from an onboard compressor (or external source) drives the hammer piston, delivering rapid blows to the drill bit. Simultaneously, the rotary head rotates the drill string, ensuring even bit wear and efficient rock fragmentation. The feed system applies optimal thrust to maintain bit contact, while the flushing air removes cuttings from the hole. The crawler chassis provides mobility, and the dust collector captures airborne particles. This method achieves high penetration rates in hard rock with minimal energy loss, making the KL511 ideal for open-pit blast hole drilling.
