How to Use Reverse Circulation Drill Machine for Mining Exploration and Deep Borehole Construction Applications: Complete Guide

Step 1: Initial Setup and Installation

Begin by selecting a level area on your job site. Use the hydraulic walking system to position the rig over the drilling point. Connect the 220V power supply to the main control panel. Check all hydraulic hoses for secure connections. Fill the hydraulic reservoir with recommended fluid if not pre-filled. This setup process took our team about two hours, including calibration of the guided alignment system. The manual provides clear diagrams, but having a helper for hose routing is beneficial.

Step 2: First-Time User Guide

Power on the rig using the main switch. Familiarize yourself with the control panel, which has labeled levers for rotation speed, feed pressure, and walking controls. The interface is not digital but uses analog gauges for pressure and torque. Start the hydraulic pump and let it idle for five minutes to warm up the fluid. Our first startup was smooth, though we recommend a quick check of all functions before attaching the drill string.

Step 3: Core Functions and Daily Use

For reverse circulation drilling, attach the double wall drill rods. Start rotation at a low speed and gradually increase feed pressure as the bit penetrates. The material transport system will bring cuttings up through the inner rod. Monitor the torque gauge; if it spikes, reduce feed to prevent stalling. For efficient cycles, maintain a steady rotation speed of 30-50 RPM depending on rock hardness. Our best results came from using consistent pressure rather than aggressive force.

Step 4: Advanced Techniques

Experienced operators can optimize cycle times by adjusting air pressure in the reverse circulation system. For deep boreholes beyond 150 meters, use a shorter initial rod string to establish the hole before adding length. This reduces stress on the mast. Another pro tip is to pre-lubricate the rod joints to reduce wear during long runs. The reverse circulation drilling rig for sale includes customization options, so you can request a higher torque motor for extremely hard rock.

Step 5: Maintenance and Care

After each use, flush the double wall rods with water to remove debris. Check hydraulic fluid levels weekly and listen for unusual pump noises. The mast pins should be greased every 50 hours of operation. Store the rig in a covered area to protect the hydraulic components from rain and dust. Our maintenance routine took about 30 minutes per day and prevented major issues.

Step 6: Troubleshooting Common Issues

If the drill stalls, check for blockages in the rod system. Low torque often indicates hydraulic fluid contamination. For alignment issues, recalibrate the guided alignment system using the manual. The reverse circulation drilling machine pros and cons include the fact that support is available via WhatsApp for Chinese language queries, but a local mechanic can handle most troubleshooting. Our team resolved a minor hydraulic leak by tightening a fitting, which took under 10 minutes. For more setup tips, read our drilling equipment maintenance guide.
