Working Principle

The Kaishan KT25 operates on the down-the-hole (DTH) drilling principle. A pneumatic hammer is positioned at the bottom of the drill string, directly impacting the rock with high-frequency blows while the rotary head turns the string. Compressed air is supplied by a separate air compressor (not included) to power the hammer and flush cuttings out of the hole. The rig's hydraulic system drives the rotary head, feed chain, and track motors. The operator controls the drilling process from an ergonomic panel, adjusting rotation speed, feed force, and air volume to match rock conditions. The automatic rod changer adds or removes rods as needed, allowing continuous drilling to the desired depth. This method ensures fast penetration and straight holes in hard rock formations.
