Working Principle

The Kaishan KZ5 operates on the Down-The-Hole (DTH) drilling principle. A diesel engine drives the hydraulic system, which powers the rotary head and the crawler tracks. The rotary head rotates the drill string, while compressed air is supplied through the string to a DTH hammer located just above the drill bit. The hammer's piston strikes the bit at high frequency, and the bit crushes the rock through impact and rotation. The air also flushes cuttings out of the hole through the annulus. The feed system applies optimal weight on bit for efficient penetration. The dust collector captures airborne particles at the collar, ensuring a cleaner work environment. The operator controls all functions from an ergonomic panel, allowing precise adjustment of rotation speed, feed force and air volume to match rock conditions.
