A YG RC-300 reverse circulation drill rig crossed the Indian Ocean and arrived at a gold mine exploration site in Ghana, West Africa. This was a routine equipment export, but also an opportunity to prove the performance of YG reverse drilling machine under complex overseas working conditions. Ghana has high temperatures and dusty conditions in the dry season, with underground formations mostly alternating between pebble layers and hard granite, which places high demands on the heat resistance, dustproof ability and drilling efficiency of drilling equipment. After being put into construction, this YG RC-300 has gradually won recognition from mining customers with its continuous and stable operation.【WhatsApp/WeChat/Phone】+86 13837122632

Customer Source and Initial Contact
The Ghanaian customer is a medium-sized mining company engaged in gold exploration. The client searched for rc drill rig for sale via search engines, visited the YG official website, and was attracted by the detailed parameters and application cases of the YG RC-300. On the same day, the customer sent an inquiry, focusing on the drilling efficiency in hard rock and whether the equipment could adapt to the high-temperature and dusty environment during Ghana’s dry season. The YG sales team provided a targeted technical plan and video demonstration within 24 hours, quickly building trust.
Communication Details and Closing Process
In two subsequent video conferences, the customer raised three core concerns: whether the equipment could drill stably without mud, whether maintenance was convenient, and how after-sales parts supply for reverse circulation drilling rig for sale would be guaranteed. The YG team demonstrated the air pre-filter (filters over 90% dust) and full hydraulic system equipped on the YGRC-300 on site, and promised English operation manuals, remote guidance and stock of common spare parts. The customer also tested the operation convenience of the hydraulic manipulator and auxiliary winch, and was very satisfied with the reduced labor intensity. After three weeks of technical negotiations, both parties signed the contract. It took only 40 days from payment to shipment to Tema Port. This rc drilling machine became the main exploration equipment at the customer’s mining area.
Why the Customer Chose YG Reverse Circulation Drill Rig
The customer finally chose YG reverse circulation drill rig mainly for the following advantages:
- Full hydraulic drive, adaptable to high temperatures: Key hydraulic components are imported or joint-venture products with excellent heat balance control, ensuring stable operation even above 40°C in Ghana’s dry season.
- Telescopic mast with jack function: The moving frame can be used as a hydraulic lifting jack, doubling the capacity for casing extraction and downhole accident handling, greatly reducing construction risks.
- Manipulator and auxiliary winch reduce labor intensity: The hydraulic manipulator for drill pipe adding and auxiliary hydraulic winch make operation safer and easier.
- Outstanding cost performance: Compared with European and American brands, the price and maintenance cost of this reverse drilling machine are significantly lower. The customer said frankly: “With the same budget, buying YG allows us to equip an extra set of drilling tools and spare parts for three years.”
Real Application Scenarios and Data Results of Reverse Circulation Drill Rig
After arriving in Ghana, the equipment was deployed at a gold exploration site in the Western Region. The formation here consists of a 5-meter weathered crust overburden, underlain by hard granite. The YG RC-300 reverse circulation drill rig adopted air reverse circulation DTH hammer drilling, with actual performance as follows:
- Drilling efficiency: In granite formations, the drilling efficiency remained stable at 16–22 m/h, with daily footage exceeding 130 m — more than 10 times higher than the old equipment (8–10 m/day).
- Drilling depth: The first borehole reached 286 meters in just two and a half days, while similar holes previously took more than a week.
- Sample quality: Cuttings were collected continuously through a cyclone separator without cross-contamination, and test results were highly consistent with actual ore grade.
- Equipment stability: No shutdown due to failure occurred during two months of continuous operation. The Cummins diesel engine and hydraulic cooling system worked normally at 42°C in Ghana’s dry season.
The customer’s technical manager commented: “This machine has reduced our single-hole drilling time by 70%, and there have been almost no downhole accidents.”
Operation Experience and Customer Reviews of RC Drilling Machine
In addition to efficiency improvement, the customer highly praised the operation convenience of the YG RC-300. All control handles and instruments are concentrated on the console, allowing one person to complete drilling, pipe handling, moving and other actions. Four hydraulic outriggers ensure stability on uneven ground. The customer specially mentioned that the remote video guidance provided by YG enabled local workers to master operation skills in just two days.
