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.
Reverse circulation drilling is similar to air core drilling as the samples that are drilled up from the earth are not simply placed onto the surface surrounding the machine but the samples are instead shot up into the hollow pipe of the machine. This is one of the biggest benefits of the reverse circulation drilling procedure because it prevents the samples from being contaminated from other materials that it might come into contact with once it has been removed from the earth.

Product 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.

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.
At sollroc, customer satisfaction is our top priority. Our sales team takes a proactive approach in meeting customers' needs. We take the time to get to know you and learn about your operations so we can better assist you. We strive to meet customers' needs by supplying the tools and equipment you need when you need them, providing product support, and following through with excellent customer service every step of the way.
