Product Introduction
Reverse Circulation, or RC Drilling, is a clean and environmentally friendly method of deep foundation installation. It employs dual-wall drill rods, comprised of an outer drill rod with an inner tube . As the sections of drill rod are screwed together, the inner tubes overlap and seal with O rings. This provides a continuous path for the drill tailings to be transported from the bit face to the surface.
The reverse circulation drilling method has the capability of reaching depths of 500 meters. A pneumatic hammer-like device is used to hammer into the earth to remove rock samples which are then pushed up into the mining machine using compressed air. The samples are collected in a sample bag which is located within the machine. More than one sample bag can be collected which allows for more of a variety of samples to be analyzed. Sample bags are usually marked to show the location from which the sample was taken as well as the depth from which the samples are extracted.

Product Features
1.Although the process can be costly the overall drilling costs can actually be reduced by up to 40% when using reverse circulation drilling.
2.Results from reverse circulation drilling can be revealed much faster as the completion of the drilling process is done quickly.
3.The method is safe to use and requires fewer man hours.
4.Reverse circulation drilling requires less water than other mining methods.
5.Reverse circulation drilling is simple and easy.
6.Samples can be easily arranged into boxes stating where the sample was collected and at what depth the sample was collected which will help those studying the samples to pinpoint exactly where the mineral deposit is located. This will help a mining company or a group of researchers to quickly and easily locate the exact area and depth from which the sample was discovered.
