About Project
The roller cone drilling rig has the advantages of large drilling diameter, high efficiency, large production capacity, low operating cost and energy consumption, high degree of mechanization and automation, and is suitable for drilling operations of various hardness rocks from f4 to f20. It is a large-aperture blasthole drilling equipment widely used in large and super large open-pit mines in the world today.
High axial pressure, high torque, high speed, and large bore diameter provide excellent production efficiency for your mining operations
Electric motor, diesel engine dual power system, optional high and low dual pressure or low wind pressure air compressor, high efficiency, energy saving, green and environmental protection Constant power variable electro-hydraulic proportional control system is adopted to automatically adjust the operating parameters according to the rock formation Equipped with three-point floating leveling chassis and high-strength truss drilling frame, it has high reliability Two rock drilling modes of cone rotation and down-the-hole impact, with good adaptability to working conditions and wide adaptability to rock formations
1. Rotary drilling rig SWDRT250 adopts the dedicated hydraulic retractable crawler chassis and large diameter slewing bearing to provide extraordinary stability and transport convenience.
2. Rotary drilling rig SWDRT250 adopts the imported electric control turbo-supercharged engine to provide strong power and conformity with Euro III emission standard.
3. With the hydraulic pressure system adopted threshold power control and negative flow control, the system acquired high efficiency and higher energy conservation.
4. Rotary drilling rig SWDRT250 design meets the requirements of the CE directive, safety guarantee, construction safer.
