We are proud to showcase the JRC200 Reverse Circulation Drilling Rig in action, conquering challenging mountainous terrain in the Middle East! Our client shared impressive on-site photos, demonstrating its power, precision, and adaptability in demanding conditions.
Key Features & Performance Highlights
1. 200m Depth Capacity & 115–143 mm Hole Diameter
The JRC200 meets drilling requirements for depths up to 200 m and hole diameters of 115–143 mm. Our Middle Eastern customer successfully completed drilling to a depth of 180 m with a 127 mm diameter, obtaining high-quality samples efficiently.
2. Powerful & Convenient Power System
Equipped with an 85 kW Yunnei engine, the JRC200 can achieve drilling angles from 45° to 90°. To improve operational efficiency and reduce time and cost, our customer selected a power head with 0–90° reversal, enabling easier loading and unloading of drill pipes. Optional features for other customers include hydraulic clamps, hydraulic blowback valves, and winch hydraulic reversal.
3. Complete Sampling System
The sample splitter, cyclone, and wind box work together to ensure accurate sample collection, splitting, and storage. The sample splitter evenly divides collected rock cuttings, proportionally splitting them (e.g., 1/2, 1/4) to eliminate human error and maintain consistent mineral composition, ensuring accuracy and representativeness for subsequent testing and analysis.
4. Equipped with JAC29/23 Air Compressor (29 m³/min, 23 bar)
The reverse circulation system, combined with DTH technology, uses the air compressor to provide compressed air for impact and dust collection. In operation, the reverse circulation hammer and double tube design allow compressed air to enter between the two tubes, while dust and cuttings are discharged through the inner tube. This process delivers clean, dry rock chips for sampling, meeting customer requirements.
The JRC200 continues to prove itself as a compact yet powerful RC drilling solution, ideal for mining exploration, geotechnical surveys, and operations in remote or challenging terrain.
