Performance Features
A DTH (Down-the-Hole) hammer is a drilling tool used in various industries, particularly in mining, construction, and exploration drilling. It is designed to produce a powerful hammering action, which is transmitted to a drill bit to break rock formations and create boreholes.Here's how a DTH hammer typically works:
Setup: The DTH hammer is attached to the end of a drill string, which consists of multiple drill pipes connected together.
The drill string is lowered into the borehole.
The drill string is lowered into the borehole.
Compressed Air: High-pressure compressed air is supplied to the DTH hammer through the drill string. The air is directed into the hammer's internal chamber.
Valve Mechanism: Inside the DTH hammer, there is a valve mechanism that controls the flow of compressed air. The valve
mechanism opens and closes rapidly, allowing the air to pass through and create a series of powerful blows.
mechanism opens and closes rapidly, allowing the air to pass through and create a series of powerful blows.
Percussion: As the compressed air flows through the hammer, it strikes an internal piston, known as the driver or striker.
The striker moves downward, striking the top of a drill bit.
DTH Bit: The drill bit, connected to the DTH hammer, receives the impact energy from the striker. The intense hammering
action of the bit against the rock formation causes it to break and create a borehole.
Rotation: In addition to the hammering action, the drill string is often rotated to facilitate the drilling process. The
rotation helps to clear debris from the borehole and maintain the straightness of the hole.
Extraction: After drilling a certain depth, the DTH hammer and drill bit are removed from the borehole. The process may
involve adding more drill pipes to the drill string as the borehole gets deeper.

DTH hammers are known for their efficiency in drilling hard rock formations and providing a high rate of penetration. They are available in various sizes and designs to suit different drilling requirements. The selection of the appropriate DTH hammer depends on factors such as the type of rock, desired hole diameter, drilling depth, and required drilling speed.
