Working Principle
The Kaishan CDC-450J operates on a hydraulic drilling principle, utilizing either DTH (down-the-hole) hammer or mud rotary methods. In DTH mode, compressed air is directed to a hammer at the bottom of the hole, which rapidly strikes the rock to create fractures. The cuttings are flushed out by the air stream. In mud rotary mode, a drill bit is rotated by the hydraulic top drive, while drilling fluid (mud) is pumped down the drill string to cool the bit and carry cuttings to the surface. The rig's hydraulic system powers the rotary head, feed chain, and crawler tracks, allowing precise control of rotation speed and feed force. The operator controls all functions from the cabin, ensuring efficient and safe operation. The engine drives the hydraulic pumps, which distribute power to the various components. This dual-method capability makes the CDC-450J adaptable to different geological conditions, maximizing productivity.
