Multi-functional Air driven circulation drilling machine

A reverse circulation drill is a type of Drilling Equipment,also called Reverse Circulation Drilling Machine used to extract rock and soil samples from the ground. It works by using a combination of air and water to create a reverse circulation of fluid that brings cuttings to the surface.

The machine consists of several key components, including the drill bit, drill pipe and drilling fluid system. The drill bit is attached to the end of the drill pipe and is used to break up rock and soil. The drilling fluid system pumps a mixture of air and water down the drill pipe, creating a reverse circulation of the fluid.

As the drilling fluid circulates, it brings cuttings back to the surface through a separate pipe called the annulus. Once the cuttings reach the surface, they are collected and analyzed to determine the composition of the rock and soil.

Reverse circulation drill is a common drill used in mineral exploration and geotechnical engineering. In some cases, they are more popular than other drilling methods because they offer a faster and more efficient way to collect large amounts of rock and soil samples. In addition, since the cuttings are contained in the drilling fluid system, the reverse circulation method helps to minimize sample contamination.
