As part of Kaishan's proven KG series, the KG520 integrates a powerful diesel engine, a heavy-duty hydraulic system, and a durable undercarriage to deliver reliable performance in the most challenging geological conditions. It is capable of drilling holes from 90 mm to 165 mm in diameter, making it a versatile choice for both production drilling and exploration tasks. ## Technical Features The KG520 features a high-torque rotary head and a robust feed system that ensures stable penetration rates in hard rock. The hydraulic system is designed for smooth and precise control of feed force, rotation speed, and tramming, allowing operators to adapt quickly to changing rock formations. A high-efficiency dust collector reduces airborne particles, improving worksite safety and environmental compliance. The rig is equipped with a comfortable, ergonomic control panel that centralizes all drilling and tramming functions, reducing operator fatigue during long shifts. The crawler undercarriage provides excellent stability and mobility on rough terrain, while the articulated boom enables accurate positioning of the drill hole. ## Applications The KG520 is widely used in open-pit mining, quarrying, road construction, and water well drilling. In mining, it handles production drilling and pre-split drilling with precision. In quarries, it delivers consistent performance in granite, limestone, and basalt. For water well projects, the KG520 can be equipped with optional accessories to drill deeper holes, making it a flexible solution for rural water supply and irrigation. Its compact design also makes it suitable for urban construction and foundation work where space is limited. ## Reliability and Service Kaishan is a globally recognized manufacturer of drilling equipment, and the KG520 is built to withstand continuous operation in harsh environments. The rig's components are sourced from reputable suppliers and assembled under strict quality control. Kaishan's worldwide service network provides technical support, operator training, and genuine spare parts to ensure maximum uptime and low total cost of ownership.

Working Principle

The Kaishan KG520 operates on the Down-The-Hole (DTH) drilling principle, where a pneumatic hammer is positioned directly behind the drill bit at the bottom of the hole. High-pressure air is delivered through the drill string to drive the hammer's piston, which strikes the bit with high-frequency impacts. Simultaneously, the rotary head rotates the drill string, allowing the bit to crush rock efficiently. The air also serves to flush cuttings out of the hole, keeping the bit clean and preventing clogging. The feed system applies optimal force to maintain bit-to-rock contact, while the hydraulic system controls rotation speed and feed rate based on formation conditions. The crawler undercarriage enables precise positioning and stable operation during drilling. This combination of impact, rotation, and flushing results in fast penetration rates and extended bit life, making the KG520 ideal for hard rock drilling.
