Central Sample Collection Reverse Circulation Hammer For Geologic Exploration

Reverse Circulation Hammer Introduction


Reverse circulation drilling is also called central sample collection or double-wall drilling. This type of drilling usually uses a double-wall drill pipe. Drilling force is high wind pressure gas, which enters into the hammer through the gap between the outer pipe and the inner pipe. The hammer hit the drill bit to break rock, and the broken rock is collected into the pores on the drill bit surface, and then the rock samples are collected through the sample collection pipe and the drill pipe.
