5' SRE545 Reverse Circulation RC Drill Bit For Sample Blasting Hole Drilling Product Introduce: RC drilling is a technique used in the majority of stages of mine development. As it is cheaper than diamond core drilling, it is often used in first stage exploration mining to delineate a potentially extractable ore body. It is also preferable to RAB or air-core drilling when trying to reach great depths, but RC drilling is slower and more expensive than either of these two

Product Description

5'' SRE545 Reverse Circulation RC Drill Bit For Sample Blasting Hole Drilling

Product Introduce:

RC drilling is a technique used in the majority of stages of mine development.
As it is cheaper than diamond core drilling, it is often used in first stage exploration mining to delineate a potentially extractable ore body. It is also preferable to RAB or air-core drilling when trying to reach great depths, but RC drilling is slower and more expensive than either of these two methods.RC drilling is also consistently used during in-pit grade control and the development stage of an ore body.

Adavantages:

1. No contamination
2. Higher Production
3. Dry Sample
4. Higher Sample Recovery

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.

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
