High efficiency reverse circulation drilling machine

Reverse Circulation Drilling Machine,air lift rig is a drill that uses a reverse circulation method to extract drill samples from the surface.

 In this method, drilling fluid is pumped down the drill pipe and discharged through the bit. 

The drilling fluid then carries the cuttings back to the surface through the annulus between the drilling  pipe and the well wall. 

This method is commonly used in mineral exploration and water well drilling because it allows for efficient and rapid drilling and provides high-quality samples for analysis.

 A reverse circulation rig usually consists of a drill pipe, drill bit, drilling fluid pump, and a collection system for drilling samples.
