D450D Φ115-152mm Integrated Open-pit Down-the-hole Mine Drilling Rig

As a leading drill rig for medium-sized mining operations, the RuiXin D450D demonstrates exceptional stability in harsh conditions: when drilling 138mm-diameter holes in hard rock formations—where rock hardness often exceeds 80 MPa—it can stably maintain a working pressure of 20 bar, ensuring continuous and efficient penetration without pressure drops or operational interruptions.

This reliable performance is further reflected in its operational metrics: whether in terms of drilling output (measured by daily hole footage) or fuel consumption per linear foot drilled, the RuiXin D450D consistently ranks among the top performers in its class. Its ability to balance high productivity with cost efficiency has made it a preferred choice for medium-sized mining projects seeking both operational effectiveness and economic returns.
