The DTH hammer operates through compressed air, which is pumped through a series of valves and chambers within the hammer. When the air pressure builds up, it drives a piston that strikes the drill bit, creating a powerful force that breaks the material. This process continues in rapid succession, allowing the drill bit to penetrate the ground efficiently. The design of the DTH hammer allows for a larger drop height of the piston than traditional rotary drills, resulting in higher impact energy and better drilling performance.
