Kaishan Surface Drilling Rigs/Crawler DTH Drill Rig with Integrated Air Compressor Series
KT25
The KT25 integrated surface DTH drilling rig can drill vertical, inclined and horizontal holes and is mainly used in large open-pit mines and stonework for blast holes and pre-splitting holes. A Cummins non-road diesel engine is the single power source; through two-end output it drives both the screw compressor system and the hydraulic transmission system. The rig is equipped with an automatic rod handling system, a hydraulic dry dust collection system with wet dust removal as an option, automatic electro-hydraulic anti-jamming and floating joints protecting the drill rod threads. It is characterized by excellent integrity, high automation, efficient drilling, environment-friendliness, energy conservation, simple operation, flexibility and travelling safety.
Drilling capability — Rock hardness
f=6-20
Drilling capability — Drilling diameter
152-203 mm
Drilling capability — Depth of economical drilling
35 m / 36 m
Travelling speed
3.0 km / h

Recommended packages
Air compressor match
Integrated rig — the screw air compressor is built into the machine, so no separate compressor unit is needed. Only confirm the onboard compressor rating (pressure and flow) matches your hammer size.
DTH hammer & bits
Match the DTH hammer class to your hole diameter: K3/K30C for 90-105 mm, K5/K50 for 135-165 mm — see the DTH hammer series page for the full ladder.
