Reverse Circulation Drilling Rigs
The reverse circulation drilling rig is an efficient, environmentally friendly, and versatile rig mounted on crawler tracks. It uses advanced reverse circulation drilling technology, allowing rock dust to be effectively collected through a dust collector. When air is used as the circulating medium, the system enables water-saving drilling and prevents environmental contamination. Cuttings can also be collected via a cyclone separator for geological sampling and analysis, making it an ideal choice for geological exploration and other deep-hole drilling applications.
The reverse circulation drilling rig can perform compressed-air reverse-circulation drilling across a wide range of ground conditions. Lifting and compensation of the drill mast, drill pipe, rotary and feed systems, outriggers, hoisting operations, and crawler travel are all hydraulically driven, significantly reducing labor intensity while improving drilling efficiency and construction quality.
Reverse circulation drilling technology uses compressed air to drive the RC hammer and bit to break the rock. Rock samples are returned upward through the RC bit, hammer, and drill pipe to the cyclone, where the sample separator removes cuttings from the air-water mixture. The collected samples are then used for geological analysis. This drilling method is known as reverse circulation (RC) drilling.
