Product Description

Product Introduction:

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.
Backed up with a large industrial experience in this domain, we are offering an optimum quality range of RC Reverse circulation Bits. The offered bits are manufactured by utilizing certified quality materials and latest technologies in the strict vigilance of our highly skilled professionals. These bits are widely used in various drilling and mining applications to take the sample of stone and sand. Furthermore, our robust range of RC Reverse Circulation Bits is available in various specifications as per the need of our valuable patrons at lowest prices.

Product Advantages:
1. The internal structure is very simple with components of high rigidity, thus ensuring long life and easy maintenance of the hammer.
2.The collection tube adopts an intergrative design and can be replaced without disassembling the hammer. With carburizing treatment, it has good abrasive resistance.
3.Equipped with bits designed with patent. Simply by replacing the drill bit, the same hammer can drill holes of different sizes ensuring that the sample is not contaminated.
4.In difficult condition such as loose soil, hard rock and plenty of water exists, sampling can be done well.

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.
