- Dust collection system
- DTH hammer and bit
Working Principle
The Kaishan ZT11 operates on the principle of down-the-hole (DTH) drilling, where a pneumatic hammer is placed directly behind the drill bit at the bottom of the hole. High-pressure air from an onboard compressor or external source drives the hammer's piston, delivering rapid impacts to the bit while the rotary head turns the drill string. The combination of impact and rotation breaks rock efficiently, and the exhaust air flushes cuttings out of the hole. The rig's hydraulic system controls feed force, rotation speed, and tramming, allowing the operator to adjust parameters for different rock conditions. The track undercarriage provides mobility, and the dust collection system captures airborne particles for a safer work environment. This method ensures high penetration rates and straight holes in medium to hard formations.
