Product Information:
Matching for DTH hammer.
DTH hammer is a part of down hole drilling rig, which is a working device of down hole drilling rig. Submersible hole impactor is divided into low air pressure submersible hole impactor, medium air pressure submersible hole impactor and high air pressure submersible hole impactor.
Applications:
• Underground mining
• Quarry benching operations
Advantages:
• High drilling efficiency, long drilling tool life, submersible impactor drilling, the medium is air, no flushing media recovery and disposal problems, reducing the auxiliary time.
• Low cost of use, the submersible impactor requires small shaft pressure and low speed of the drilling rig, while the torque is low, so the natural power consumption is small, and the diameter of the drill pipe is relatively thin, easy to install and disassemble, and the service life is long.
