4. Key points of spiral sand washing machine operation and maintenance

Daily management

Check the wear of spiral blades every week (＞5mm needs to be replaced)

Replenish grease for bearings every 400 hours of operation

Fault handling

When the current fluctuates abnormally, the machine should be stopped immediately for inspection

The overflow port needs to be cleaned if the screen is blocked (≤4 hours/time)

Winter protection

The water tank must be emptied after shutdown

Replace the reducer with winter special lubricating oil
