Dual pipe RC Drilling Black Color SRC543 4'' RC Hammer OD116mm For Mining Use
Product Introduce:
Reverse circulation is achieved by blowing air down the annulus of the rod, the differential pressure creating air lift of the water and cuttings up the inner tube which is inside each rod. It reaches the deflector box at the top of the drill string then moves through a sample hose which is attached to the top of the cyclone.

Adavantages:
1.Samples obtained via RC drilling are free of contaminants
2.The samples are collected at the drill and sent directly to the lab to be assessed
3.RC sampling requires less handling than other methods
4.Less handling results in cost reduction and faster turnaround times
5.The reliability of the cuttings produced during RC drilling is an industry asset. RC grade control is the most cost 6.Effective and efficient method to differentiate between waste rock and minerals.

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
