Product Description

Reverse Circulation (RC) Drill Rig for Mining and Rock Exploration

This heavy-duty Reverse Circulation (RC) drill rig is engineered for efficient and

reliable mineral exploration in demanding mining environments. It is specificallydesigned to provide high-quality, uncontaminated rock and soil samples from

significant depths.

The core of its operation is the reverse circulation system, which utilizes a dual-walldrill pipe. Compressed air is injected down the annulus between the inner and outertubes, driving a down-the-hole hammer for rapid penetration. The cuttings are thenpneumatically conveyed up the inner tube in a continuous, sealed flow. This method

preserves sample integrity by minimizing contamination and material loss, delivering

representative samples critical for accurate geological analysis.Built for rugged terrain and mining operation, this robust rig offers powerful drilling

capabilities, excellent depth capacity, and high recovery rates. It is an indispensable

tool for greenfield exploration, resource definition, and grade control in open-pit mines,

ensuring dependable performance in the most remote and challenging locations.
