Reverse circulation drilling (RC) is a fairly simple, fast and efficient sampling method for in-pit grade control while maintaining good sampling quality. The RC drilling method not only prevents cross contamination but also enables a large number of sample bags in a short amount of time. Sample bags are labelled with the same location and depth information,and can be sent to a laboratory immediately after or during drilling.If done correctly, RC drilling will significantly reduce overall drilling costs and environmental impact.
An RC-equipped drill rig can be quickly converted to production drilling. Our rigs support inclined drilling, which makes it easier to find the boundaries of the ore body.
Our reverse circulation RIGS are efficient and fast. Paint the whole rig to protect the rig. The rig has a long service life. Our separator has a drying function so that the sample is taken out in a dry powder.Further analysis yields fast, reliable information about mineral deposits that allows you to selectively pinpoint zones for drilling and blasting for maximum ore recovery and greater profit per ton.

Features:
RC-200,RC-300,RC-500,CZRC-500 Reverse Circulation Drilling Rig is a crawler-mounted, compact rig specifically designed for reverse circulation drilling at depths down to 200-500 meters.
1. The latest intelligent laser cutting technology
Cutting workshop introduced the latest laser cutting machine, from the drawing to the com-pletion of the production of tooling all realize intelligence. Ensure that all parts of the machine are handled with precision and detail.
2. Decomposing spray painting process
Always adhere to the decomposition spray painting process, such advantages are: ①.to ensure that each side of the machine is painted; There will be no spray paint surface overflow. ②.adhere to rust removal, oil removal, primer, color paint, top paint and other processes to ensure a high level of product appearance.
3. More user-friendly design
We use a more user-friendly design with a longer lifespan. For example, more than 300 power head bidirectional 6 slider design, 300 power head bidirectional four slider design, more stable; Can quickly disassemble the slider, more conducive to user maintenance; The front and back legs are all equipped with dust cover, longer service life, etc.
