RE531 Superior Quality Alloy Steel Reverse Circulation RC Drill Bit for Sampling
Product Introduce: The RC products have the unique ability tobring all cuttings up the
center of the hammer and drill string to be safelycollected at the
surface, which is essential in today’s environmentallyconscious
society. The RC bits are the tool cutting rock. All of our RC
DTHbits are made of superior quality alloy steel and tungsten
carbide.
Adavantages: 1. High drilling penetration rates. 2. Indirect cost reductions gained from a simplified sampling process. 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. Requires less water than diamond drilling. Technical Parameters RC bits Model SRC531
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
