Product Description

Product Description

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.

Our hammer and bits are made of high quality alloy steel with advanced heat treatment to assure the good drilling performance and long service life.,all the products are manufactured as per the international standard. They are widely used by our customers all over the world

 

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.

Our Advantages

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.
