RC series reverse circulation Hammer is the latest developed product of our company. It is mainly used for deep exploration drilling and ore grade control.
The reverse circulation drilling method has the capability of reaching depths of 500 metres. 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 analysed. 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 Advantages:
1.Well-suited for difficult terrains;
2.High penetration rates, and it has minimal environmental impact
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.

Working principle
1. With the piston resting on the percussion bit and the hammer closed up in the drilling position, high pressure air is directed into the bottom chamber of the Hammer and the piston lifts. This commences the piston cycle.
2. As the piston travels upwards it forms the top chamber by forming a seal with the inner tube and the ID the piston. Further movement seals the port that feeds the bottom chamber and also simultaneously releases the seal on the bottom chamber allowing the air to expand and exhaust down the splines of the percussion bit. At the same time the Top chamber port is opened which feeds the high pressure air into the previously formed top chamber thus increasing the pressure above the piston and forcing it back down.
3.During the down cycle or power stroke the piston reseals the bottom chamber on the piston bearing bush thus stopping the exhaust air and creating a chamber of high pressure air below the piston which forces the piston back up the hammer.
4. Lifting the hammer of the bottom of the hole allows the percussion bit to slide down the drive sub also allowing the piston to slide down the hammer and rest on the piston bearing bush. The piston strike face and the strike face of the percussion bit can now not come into contact thus allowing the free flow of high pressure air directly through the hammer without the hammer cycling.
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.
