Introduction

For small and medium-scale gold miners, the gold grinding machine (also known as the wet pan mill) is an essential piece of equipment for gold concentration and fine grinding. However, like any mining equipment, its performance and lifespan depend heavily on regular maintenance.

Proper care not only reduces breakdowns but also improves grinding efficiency and lowers operation costs.

Here are 5 proven maintenance tips to help you extend the life of your gold grinding machine and keep your operation running smoothly.

1. Regular Lubrication

Lubrication is the foundation of all equipment maintenance.

Use high-quality gear oil or grease according to the manufacturer’s recommendation.

Check oil levels every 8–10 working hours.

Replace lubricating oil regularly to prevent contamination by dust and water.

Proper lubrication keeps the transmission system running smoothly and prevents wear on rollers and bearings.

2. Inspect Wear Parts Frequently

The rollers, grinding plates, and bearings are wear-prone parts of a wet pan mill.

Inspect them weekly for cracks, uneven surfaces, or excessive wear.

Replace damaged parts immediately to avoid chain failures.

Keep a set of spare parts ready to reduce downtime.

Timely replacement prevents costly damage and ensures stable output quality.

3. Keep the Machine Clean

After each shift, remove residual mud, gold sand, and ore particles.

Use water or compressed air to clean the grinding pan and rollers.

Avoid leaving material residues that could harden and cause imbalance.

A clean machine operates more efficiently and avoids corrosion.

4. Check Alignment and Tightness

Vibration and long-term use can loosen bolts or shift mechanical parts.

Check the tightness of screws, belts, and couplings regularly.

Ensure the rollers and grinding plates are properly aligned.

Proper alignment maintains grinding uniformity and reduces mechanical stress.

5. Operate Within Rated Load

Overloading is a common cause of premature wear.

Do not exceed the recommended feeding capacity.

Maintain steady feeding and avoid sudden material surges.

Stable operation helps extend the wet pan mill’s service life and ensures consistent gold recovery.

Conclusion

A gold grinding machine is a valuable investment in your mining operation. With proper maintenance—regular lubrication, inspection, cleaning, alignment checks, and careful operation—you can significantly extend its lifespan and keep it working efficiently for years.
