    KT7 Integrated open hole drill

    "Kaishan" brand KT7 integral high-pressure open-air DTH drilling rig is an advanced drilling equipment which combines DTH drilling system with screw air compression system.

    1. Detailed information

    KT7 Integrated open hole drill:

    "Kaishan" brand KT7 integral high-pressure open-air DTH drilling rig is an advanced drilling equipment which combines DTH drilling system with screw air compression system. It uses a six-cylinder diesel engine to provide power for the two systems, with compact structure, good integrity and easy movement. The single-stage compressed high-pressure screw head equipped with core knowledge products of the drilling rig is equipped with the internationally leading Torres Y-line, which has a large flow rate (13m/min) and a high pressure (1.7MPa), providing strong power for the high-pressure pneumatic impactor. The rock drilling speed is 20% - 50% higher than that of the stroke drilling rig.

    "Kaishan" brand KT7 integral high wind pressure open-pit DTH drill is mainly used for rock drilling in stone works and open-pit mines.
