Kaishan KT12 Integrated Surface DTH Drill Rig with Air Compressor

• High-Volume 20 m³/min @ 22 Bar Flushing Power: The onboard two-stage screw air end delivers 20 m³/min airflow at 22 bar (319 psi), guaranteeing clean borehole flushing and high penetration rate (ROP) in large 115–152 mm blast holes.
• High-Torque Rock Penetration (3,450 N·m): Delivers 3,450 N·m rotary torque combined with 40 kN feed thrust, providing aggressive cutting power through tough granite, basalt, and iron ore without bit stalling.
• Heavy-Duty Cummins 264 kW Architecture: Driven by an industrial 6-cylinder Cummins QSL8.9 diesel engine directly powering both the air end and a 5-unit gear hydraulic pump group, ensuring reliable performance in high-altitude and extreme ambient conditions.

Q: What are the main performance advantages of the KT12 compared to the KT11?

A: The KT12 upgrades diesel engine power to 264 kW (versus 242 kW on KT11), expands screw compressor delivery to 20 m³/min @ 22 bar (versus 18 m³/min @ 20 bar), increases rotary torque to 3,450 N·m (versus 2,800 N·m), enlarges drilling diameter up to 152 mm (versus 140 mm), and features a heavy 6+1 carousel engineered for larger Φ76/Φ89 mm drill pipes and 4″/5″ DTH hammers.

Q: Does the KT12 require any auxiliary compressor or separate power source?

A: No. The KT12 is 100% self-contained. The 264 kW Cummins diesel engine powers all hydraulic tramming, positioning, and rotation systems while directly driving the onboard 22-bar two-stage screw air compressor, operating completely autonomously with zero trailing air hoses.

Q: Can the KT12 drill inclined and horizontal blast holes?

A: Yes. The heavy articulated drill boom offers versatile angular positioning: lifting from up 47° to down 20°, boom swing from right 50° to left 15°, carriage swing from right 96° to left 30°, and beam tilt angle of 114°, allowing efficient drilling of vertical, inclined pre-split, and horizontal toe holes.
