In placer gold deposits and surface-exposed primary deposits, ore often contains weathered clay that wraps hard ore and forms cemented blocks or slurries. If not washed properly, these clay-bound materials can directly affect the next processing stage.The gold washing machine is responsible for the most arduous task in alluvial gold mining — ore washing and desliming. If the washing machine stops working, the entire production line stops. Therefore, regular inspection and maintenance are not optional — they are the fundamental guarantee of long-term, trouble-free operation.

A consistent daily routine prevents small issues from becoming major breakdowns. First of all, check the oil level of the reducer and lubricating points before each shift. Subsequently, inspect the wear condition of wear parts such as blades, screen panels, and bearing bushes. In addition, clean accumulated debris and clay from the drum interior and screen apertures after each shutdown. Finally, observe the machine’s operation — listen for unusual noises, check for vibration changes, and monitor bearing temperatures.

Weekly & Monthly Maintenance Tasks

Beyond daily checks, scheduled weekly and monthly maintenance ensures long-term reliability:

Weekly Tasks:

• Inspect all fasteners and bolts, especially on the drum cage and screen frame — tighten any loose bolts immediately.–

• Check the lubrication of bearing seats and gearboxes; refill or change oil as needed.–

• Clean the space between rollers and roller axles to prevent material accumulation.–

Monthly Tasks:

• Replace severely worn blades and bearing bushes to maintain washing efficiency.

• Inspect the drive system alignment and tire condition (for tire-driven models).

• Check water spray nozzles and high-pressure hoses for blockages or wear.

Different types of gold washing machines require different maintenance focuses:

• Rotary Scrubber (Trommel Scrubber): Regularly check the oil volume of the reducer and the wear of the drum shell. For tire-driven models, inspect tire pressure and tread condition.

• Spiral Washing Machine (Screw Washer): The propeller blade and bearing bush are the key wear parts. Because the bearing bush is immersed in water for a long time and bears great pressure, its wear is very serious. Therefore, timely replacement of the bearing bush not only improves washing efficiency but also protects the tank body from damage.

• Trommel Screen with Washing Function: Inspect the screen panels daily for pegging or clogging, especially when processing sticky clay ores.

Many operators unknowingly shorten equipment life through these common mistakes:

• Over-lubrication: Adding too much grease can cause bearing overheating. Follow the manufacturer’s recommended grease amount and interval.

• Ignoring wear parts: Continuing to operate with severely worn blades or bearing bushes reduces efficiency and can damage downstream components.

• Skipping daily cleaning: Clay and debris left in the drum can harden overnight, making the next startup difficult and straining the motor.

• Operating without water: The washing machine must never run dry — insufficient water supply causes rapid wear of internal components.
