Tri-Cone RC System
High pressure air is forced down the annular space between the inner and outer pipes and lifts the cuttings up the inner tube. Top head drive rotates the entire drill string including the tricone roller bit. The diagram below displays the different components of the Dual-Wall RC rotary system as well as the airflow circulation within the pipe:
