Reverse Circulation ( RC ) Drilling Rig Machine DC Drilling 300 Mm Hole Size
Reverse Circulation (RC) Drilling Rig Why needs reverse circulation drilling? . When drilling the hole of diameter >250mm, which the annular area between the drill pipe and inner surface of borehole is very big. . If using direct circulation drilling method, it needs very powerful compressor with high air flow(even 2 – 3 compressors) to get enough flushing speed to below all the cuttings out of hole. . Otherwise, the cutting will stay in the hole...

500m Hydraulic Dth Track Mounted Reverse Circulation RC Drilling Rig
JRC500 Hydraulic DTH track mnounted reverse circulation mining rc drilling rig The rc drilling is to use a pneumatic hammer to drive a tungsten steel drill bit to break the rock formation. A pneumatic reciprocating piston repeatedly called a hammer, which in turn drives a tungsten steel drill bit that is used to break hard rock. When the compressed air is blown out, the pressure deviation will produce a reverse circulation, so that the cuttings...
