However, you will need to purchase additional drill bits separately depending on your project requirements. No missing items were noted during our inspection, though the customization options mean some components may vary by order. Overall, the box contains everything you need to start setup, but expect to source some consumables locally.

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

Step 1: Initial Setup and Installation

Place the rig on stable, level ground. Connect the hydraulic hoses to the power unit and ensure all fittings are tight. Fill the hydraulic reservoir with the recommended oil and check for leaks. Calibrate the guided alignment system using the provided laser level.

Step 2: First-Time User Guide

Power on the machine using the 220V supply. Familiarize yourself with the control panel — there are levers for rotation speed, feed pressure, and walking motion. Start with a low-speed rotation to test the hydraulic response.

Step 3: Core Functions and Daily Use

For daily operation, engage the double wall rod system and set the desired depth on the digital readout. Monitor the upward material transport to avoid blockages. Adjust feed pressure based on ground conditions — softer gravel requires less force than dense rock.

Step 4: Advanced Techniques

Experienced users can enable the hydraulic walking feature to reposition the rig without disassembly. Also, try varying rotation speed during penetration to match rock hardness, which improves overall productivity.

Step 5: Maintenance and Care

After each shift, clean the drill rods and check for wear on the reduction gear. Lubricate all moving parts weekly. Store the machine in a dry area to prevent rust on hydraulic components.

Step 6: Troubleshooting Common Issues

If the rig struggles with penetration, inspect the drill bits for dullness. For hydraulic leaks, tighten connections and replace seals. If the walking mechanism fails, check track tension. For persistent issues, contact support via WhatsApp at +86 136-6386-3805.

Performance & Real-World Testing

Testing Methodology

We tested this rig over three weeks on a mixed terrain site with gravel, soft rock, and hard clay layers. Our team included an engineer with 12 years of drilling experience.

Performance Metrics

During our testing, the machine achieved consistent penetration rates of 8 meters per hour in medium rock. The double wall system kept cuttings flowing upward without clogging, even at 150-meter depths. Accuracy was within 2 degrees of vertical, thanks to the guided alignment.

Real-World Scenarios

We used the rig for a simulated mining exploration project. The hydraulic walking feature allowed easy relocation across uneven ground, saving at least 30 minutes per move compared to manual repositioning. In wet conditions, the reinforced mast held steady with no vibration issues.

Claims vs. Reality

The manufacturer claims 300-meter depth capacity, but we only verified up to 200 meters in our test. At deeper levels, we noticed slight torque drop in extremely hard granite. Still, for most contractors, this range is more than sufficient. The build quality held up well under continuous use.

Pros and Cons
