DTH hammers are all simple structure, easy to assemble and disassemble, as well as reliable quality and long service life. Kingkong Drills has various hammer models suitable to drill holes from 64mm to 1000 mm (2-1/2” ~ 39-3/8”) in diameter; and come with three kind: low pressure (5 ~ 7 bars), middle pressure (7 ~ 15 bar) and high pressure (7~ 30 bars).
We Offer three types of Medium Pressure DTH Hammers that operating air pressure is between 0.7 Mpa to 1.75 Mpa. And all of the BR Medium Pressure DTH Hammers are valveless, they are
Easy to disassemble and assemble,
Ideal faster drilling speed and higher impact frequency.
Drilling Diameter: 90mm-130mm
Hammer Length: 700mm-800mm,
External Diameter: 82mm,
Impact Frequency: 25Hz.
Air Consumption: 4 M3/min(0.7Mpa);
6M3/min(1.0Mpa); 8M3/min(1.4Mpa).
Performance advantage
1, valveless air distribution. More reliable.
2, simple design of the piston, long life.
3, More efficient energy transfer, faster drilling speed, lower air consumption and lower oil consumption.
4, fewer internal parts, simple structure, longer life, less failure and easier to maintain becayse all the parts are heat treated.
Scope of application:
They are widely used for mine, quarry, road construction for the drilling and blasting work, water well drilling, slope protection, anchoring, etc.
