The DTH hammer is an integral part of the DTH drilling rig. It is widely used in the hole-forming operations for Metal mine, Underground mining, Open cut mining, Quarry, Tunneling, Water well drilling, Large-scale Construction drilling and blasting etc.
Bonmach rock drill DTH hammer included high air pressure drill DTH hammer, low air pressure DTH hammer, reverse circulation DTH hammer for rock drill etc.
Bonmach DTH hammers are latest self-designed type. It’s valveless air distribution, simple design of the piston, more efficient energy transfer, faster drilling speed, lower air and oil consumption, less internal parts, easy maintain and easy disassemble.
It has the following advantages:
Valveless air distribution. More reliable.
Simple design of the piston, long life.
More efficient energy transfer, faster drilling speed, lower air consumption and lower oil consumption.
Fewer internal parts, simple structure, long service life, less failure and easier to maintain because all the parts are heat treated.
Easy to disassemble because the tap sub, the drive chuck and the external cylinder are connected by multi-step thread.
