Downhole air hammer air lifting drilling machine

Reverse Circulation Drilling Machine /rig, also known as an RC rig, is a type of drilling rig used in mining and exploration activities. It is designed to provide efficient and effective deep hole drilling in various types of rock formations.

The machine operates by using compressed air to create a reverse circulation of drilling fluid. Drilling fluid is usually a mixture of water and additives that is pumped down the drill pipe and discharged through the bit. When drilling fluid rises to the surface, it carries with it rock cuttings and other debris.

The reverse circulation drilling method has several advantages over conventional drilling methods. It allows for faster drilling rates as cuttings are removed more efficiently. It also allows for better control of the drilling process, as the drilling fluid can be adjusted to the specific requirements of the rock formation being drilled.

Reverse circulation RIGS are usually mounted on trucks or chutes for easy transportation to the drilling site. They are equipped with powerful engines and hydraulic systems to operate the drilling mechanism and other components.

In general, reverse circulation drilling RIGS are widely used in the mining and exploration industries due to their ability to drill deep holes quickly and efficiently.
