Before a trial operation, check in detail that the components are installed correctly according to the drawings, the fasteners are firm, and whether there are obstacles around the screen body that hinder the operation of the drum screen.

2. Put the rectangular inspection door in the open position, and rotate the screening cylinder by manual turning to observe whether the comb-type cleaning mechanism has jamming or friction. If there is, it can be adjusted by adjusting the bolt.

3. Check that each bearing seat and gearbox should be well lubricated, and the gearbox oil level should be appropriate.

3. The following items should be checked for 1-2 hours of trial operation.
a. The maximum temperature of the large shaft bearing should not exceed 75℃ and the temperature rise should not exceed 45℃.
b. The tightening conditions of the tightening bolts at various places should be tightened in time if they are found to be loose.

Trial Run

1. When the trommel sand washer is running smoothly, start the feeding and discharging equipment for trial operation of feeding.

2. Close the sealed isolation cover after normal discharging (during normal operation, the sealed isolation cover should always be in the closed position).

3. Check the particle size of the discharged material, check whether there is material leakage and dust is normal.

4. After running for half an hour, carefully check all parts to see if they are normal and deal with any problems in time.

5. The operation should be checked frequently during the trommel sand washer work process. If an abnormal operation or abnormal noise is found, the machine should be shut down and checked in time to find out the reason and eliminate the fault.
