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.

The toggle mechanism is a vital part of the jaw crusher that helps in the crushing process. It consists of a toggle plate and its associated components. The toggle plate adjusts the distance between the jaw plates, allowing the user to control the size of the output material. When the movable jaw plate moves closer to the fixed jaw plate, the material trapped between them is crushed. The toggle mechanism, therefore, not only enables the crushing action but also helps in achieving a consistent output size.
