RC-drilling

Reverse circulation drilling is executed with air flow blown through drill rods, while differential pressure creates aerodynamic force which lifts water and cuttings up via a center tube contained inside any drill rod. Cuttings reach a diffuser at the top of a drilling hole, then go through a sampling hose which is connected to the head of a cyclone. Drilling cuttings are passing through a cyclone till they go out via the hole at its bottom and get collected into sampling bags.
