PR54R Reverse Circulation RC Drill Hammer with Rentention for Mine Exploration

Product Introduce:

RC drilling is commonly employed in open-cut mines and used for pit grade control and in delivering useful insight for mine planning and blasting. It has an optimal depth of between 300-500 metres.

RC grade control is extremely effective in defining boundaries between ore bodies and waste rock

RC drilling is ideal for exploration, as it delivers contaminant-free samples, which are collected at the drill itself and can be sent immediately for assessment. It also reduces handling time, which in turn can serve to reduce overall program costs.

Adavantages:

1.Reduced risk of cross-contamination. As the cuttings travel through the drill bit’s inner tube and aren’t introduced to other areas of the drill hole, the samples remain uncontaminated.
2.Faster and more efficient, reducing costs and providing greater returns. RC drilling achieves higher production rates and can achieve up to 200/300 metres per day. This means that results can be delivered to clients faster, as the drilling itself takes less time. The speed and efficiency involved also reduces manhours on the drill rig, meaning savings on overall staff hours. Thanks to the power and efficiency of the equipment, RC drilling is more resilient in harsh environments, which makes it a cheaper option overall. In fact, RC drilling has been shown to reduce costs by 25-40%.

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.

Delivery Way:

By Air, By express or By Sea
