KT7 High Pressure Integrated Drilling Rig
Our KT7 high pressure integrated drilling rig is a DTH drilling machine that combines borehole drilling system and screw air compressing system. The two systems are driven by a six-cylinder diesel engine. The whole machine has a compact structure and is easy to move. A high air pressure screw rod designed with our intellectual property is mounted on the machine. The special structure of our high pressure integrated drilling rig leads to large flow volume (13m³/min) and high air pressure (1.7MPa), providing high air pressure for the drill hammer. Thus the rocking drilling speed is 20%-50% faster than that of medium air pressure drilling machine.
Our KT7 high pressure integrated drilling rig is mainly used for the rock excavation and open-pit mining operation. Welcome to contact us if you need this crawler rotary drill.
