Zhangjiakou Xuanhua Great Wall Mining Engineering Equipment Co., Ltd. is located in Xuanhua, an ancient city in Hebei Province at the foot of the Great Wall. It is situated on Shengli North Road, adjacent to the entrances and exits of the Beijing Zhangjiakou and Danla expressways to the north, and directly leads to National Highway 110 to the south. Its geographical location is *, and transportation is very convenient. Our company has strong economic and technical strength, and is a leading manufacturer specializing in the production of lightweight series down the hole drilling rigs, with a production rate of over 80%.
The lightweight series ZQS-100B, DM-100B, and XQ-100A are a new type of high-efficiency fully pneumatic rock drilling equipment developed by our company with a single power source. This machine not only maintains the original air pressure, but also can change the air path control on this basis to achieve the ideal purpose of suitable medium air pressure. By increasing the impact energy and frequency. Ensured fast footage and high efficiency. According to the rock conditions and the requirements of drilling, blasting, and anchoring processes, the transition joint is changed to make it a multi hole down the hole drilling rig, which can drill holes with a diameter of 70-130mm. The rock can achieve high rock drilling speed within the range of Proctor hardness coefficient f=8-16. It is a rock drilling equipment for open-pit drilling of blasting holes, anchor holes, top cutting holes, pre splitting holes, and secondary crushing in early mining.
The nZQS-100D, DM-100D, and XQ-100D electric down the hole drilling machines are improved and standardized electric rotary down the hole rock drilling equipment based on the ZQS-1000B, DM-100B, and XQ-100B down the hole drilling machines. They are new, efficient, and semi mechanized drilling rods, with the characteristics of simple structure, lightweight use, short auxiliary time, and low air consumption. They are suitable for drilling large-diameter deep holes underground and mining, excavating main tunnels and preparation tunnels, and drilling shafts and ventilation holes.
The CCM600 drilling rig developed earlier by R&N company is a rock drilling equipment powered by internal combustion engines and air compressors as impactors This device has the characteristics of multifunctionality, self-propelled, and flexibility. Compared with traditional fully pneumatic drilling rigs, its major advantage is a comprehensive energy saving of 45% -50%. Another advantage is that it is used for round-trip cross operation in small and medium-sized mining operations The stability and safety of the whole machine operation have been greatly improved, making drilling operations more convenient

Our company's products have a simple and practical structure, reliable quality, and low cost, making them the preferred choice for many customers. Provide different deformation products and non-standard designs according to the usage conditions of different users. As long as it is the product you need, we will definitely strive to do it well.
Our company has friction welding machines with larger specifications in the Xuanhua area, providing various specifications of down the hole and anchor series drill rods used in the domestic market. By using the same materials as similar foreign products, adopting * processing methods, and special heat treatment processes, the lifespan of the drill pipe is greatly improved, and the user's drilling tool consumption is significantly reduced.
For many years, our company has regarded quality and reputation as our life, providing users with high-quality products and offering satisfactory services. We look forward to customers visiting and guiding us at the factory!
