Product Introduce:
Reverse Circulation (RC) drilling is one of the three main types of mineral exploration techniques. Used to compile sample rock cuttings, the drilling process relies on hollow inner tubes to transport samples back to the surface in a continuous flow, using compressed air
Basically in a Reverse Circulation Drilling Program, the drill hammer breaks up the rock as the hole is drilled. This produces gravel size rock chips, clay to sand sized sediments. The rock chips are brought to the surface by compressed air.

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.
