SRC531 Reverse Circulation Drill Hammer RC Drill Hammer for Grade Control
Product Introduce:
RC drilling is the superior method used for grade control in open pit mining operations.
Grade control is used to define the ore grades and blocks in the pit. For an exploration program, the quality of the samples is imperative for mine planning and blasting—the samples must be reliably accurate.

Adavantages:
1. samples obtained via RC drilling are free of contaminants
2. the samples are collected at the drill and sent directly to the lab to be assessed
3. RC sampling requires less handling than other methods
4. less handling results in cost reduction and faster turnaround times

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
