SRC531 102mm Reverse Circulation Carbide Drill Bits For Deep Hole Exploration
Product Introduce: A reverse circulation drilling method for drilling cuttings
carrying drill cuttings through the inner bore of the drill rod and
returning from the borehole to the ground.The liquid (gas) flow of
the reverse circulation drilling is compared with the conventional
circulation method called positive circulation, in which the
flushing medium is fed into the bottom of the drill hole through
the inner hole of the drill rod and returns to the ground along the
annular gap outside the drill rod. The speed of return is high, and
it is very strong to carry rock powder. Rocks that have been
drilled at the bottom of the hole can be discharged in time and
quickly return to the surface.
Adavantages: 1. High drilling efficiency; 2. Timely sampling and high rate of adoption are conducive to accurately assessing the stratum; 3. Using higher grade carbides for longer life; 4. Minimizes hole erosion in fragile formations 5. Drills faster through soft formations with less blockages 6. Drills straighter through consolidated and unconsolidated formations 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: About us: SOLLROC Reverse Circulation drilling (RC) ,from size 3’’ to 5.5’’, is a technique of drilling that uses dual wall drill rods that consist of an outer drill rod with an inner tube. By using compressed air to extract rock fragments sample,the samples travel through rods to a sample splitter at surface, avoiding all contact between the samples and the borehole wall that allows samples to be retrieved with minimal contamination,which is mainly used in deep hole exploration and mining grade control.
Delivery Way: By Air, By express or By Sea
