95mm RE531 Reverse Circulation RC Drill Bit for Sample Blasting Hole Drilling
Product Introduce: Reverse Circulation (RC) drilling is used to collect mineral and
rock samples quickly and efficiently using a large rotary drill and
air compressor. Reverse Circulation (or RC) drilling is one of the
most frequently used methods of drilling used across the world as
it is more cost effective and efficient then other methods of
drilling. When compared to RAB (Rotary Air Blast) and diamond
drilling, RC drilling seems to be somewhere in the middle when it
comes to cost, time, quality of samples, technique and depth.
Adavantages: 1. Direct drilling cost reductions in the range of 25% to 40%. 2. Faster completion of drill programs with quicker delivery of results. 3. Reduced man-hours at the drill with decreased exposure to potential accidents. 4. Reduced contractor activity in the mine reduces mine support burden. 5. Indirect cost reductions gained from a simplified sampling process. Technical Parameters RC bits Model SRC531

Working principle The on-board compressor delivers power to a pneumatic reciprocating
piston. The piston, in turn, drives a tungsten-steel drill bit
which is purpose designed to be able to crush hard rock. Similar to air core drilling, drill cuttings are returned to
surface inside rods. We achieve this through the use of dual wall
drill rods: an outer drill rod with an inner tube. When compressed
air is blown through the rod, the volume displaces the air, lifting
the samples to the surface. Once cuttings reach a diverter at the top of the hole, they’re
moved through a hose and around the cyclone, which slows the sample
down. From the cyclone the sample goes over a splitter that
delivers a percentage of the entire sample into a sample bag. The
exploration drilling team then collect the samples aligned to the
hole depth and lay them out for the client to log, and then
transport to the lab for assay. Detailed Photo:
