RW054 (RE054) RC Hammer
Our RC hammers are suitable for any exploration and grade control process to obtain an accurate sample with no contamination.
RC drilling hammers can in most instances carry out continuous sample collection in a fraction of the time necessary with conventional or wireline coring.
WOOKE REVERSE CIRCULATION HAMMERS
WOOKE offers reverse circulation hammers with integrated bits designed to offer a cost-effective, heavy-duty sampling system for obtaining a continuous, high-quality geological sample. By maximizing the energy output and minimizing air consumption, WOOKE'S products can assist in providing you with excellent production rates resulting in a low cost per meter drilling.
RC (Reverse Circulation) Drilling is similar to air core drilling in that the cuttings are returned to the surface through an inner tube and collected for later use. The drilling mechanism is a pneumatic reciprocating piston known as a hammer driving a tungsten carbide button drill bit to drill a borehole into the stratum. In RC drilling, compressed air is pumped into a side inlet, blown down the outer shell of a dual-wall pipe, and drives the hammer and bit to crush the rock. Once the air hits the drill bit, it flushes and cools the bit, and also creates a pressure differential that forces the air and cuttings up the center of the drill string and into the inner tube. Air and drilling cutting are then passed through the inner rod and sucked back up, through the top drive, and into a cyclone ampler. then, the rock and water are separated by the cyclone at the top, and the rock is deposited in a sample collection container.
WOOKE REVERSE CIRCULATION HAMMERS FEATURES
Advantages of Reverse Circulation Well Drilling:
- Mitigates air loss into sensitive formations
- Requires less air to evacuate cuttings
- Efficient removal of large cuttings cause less wear on tools and faster penetration rates
- Ultimate control of cuttings when discharged at the surface
- Energy-efficient and environmentally less impactful to the site
