There are two methods to identify the authenticity of our company's products. All new products that leave our factory have anti-counterfeiting code labels, and customers can verify the authenticity of the products by scanning the anti-counterfeiting code.
If compensation is possible, the after-sales service personnel will inform the customer of the appraisal results. Based on the appraisal results, compensation will be provided in the form of physical goods. If physical goods cannot be compensated, a corresponding percentage of cash will be compensated.
Drilling tools are all consumables, and every drill bit has a certain drilling meter lifespan. During use, different forms of failure will eventually occur. The drilling meter lifespan is closely related to factors such as the type of rock being drilled, drilling parameters, and the level of operation.
Common Troubleshooting Methods for Down-the-Hole Hammers
Core barrel drills are divided into two main categories: core ring-type barrel bits and non-core ring-type barrel bits. Depending on the type of strata being drilled, they can be further classified into cutting tooth barrel drills suitable for weathered bedrock and frozen soil layers, and roller cone barrel drills designed for drilling through hard bedrock.
Welded tooth roller bits are directly welded onto the roller body. Our technical sales team will communicate in depth with customers to recommend the best tooth profile based on the specific rock formations encountered in the particular project.
The detachable roller cone bit can effectively solve the overheating problem of the bearing sealing system during the welding process. The roller cone bit developed by Black Diamond has undergone reinforcement treatment in the inner cavity of the roller cone, enhancing the bearing's resistance to sticking and extending its service life.
The three-cone drill bits developed and manufactured by our company are mainly used for large-scale open-pit mining, such as in open-pit coal mines, iron mines, and various non-ferrous metal mines, as well as non-metallic mining operations. However, with the increase in varieties, they are also widely used in the hydropower sector for quarrying, foundation clearing, hydrological drilling, core sampling, and in the railway transportation sector for tunnel drilling and vertical shaft drilling in underground mines.
