Reverse Circulation 3'' Carbide Drill Bit For Deep Hole Exploration Drilling
Product Introduce: This reverse circulation drill bits are widely used in the
following applicaiton field: Geologic exploration samples, Oil
wells and ore mining, etc. And it's specifically designed to work
with RC Hammers. 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. Technical Parameters RC bits Model SRC531
Adavantages: 1. Reliable quality 2. Long service life 3. Smooth flushing effect 4. Higher productivity 5. Designed to work with RC hammers 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
