Screening technique

1 . Do the following work before driving

1 ) Check if the electromechanical equipment is good, if the screen is damaged, and if the fixing part is tight.

2 ) Check if the discharge port is blocked.

3 ) Whether the dustproof facilities are kept tight.

2. Driving sequence

1 ) After getting the driving signal, first turn on the dust collector and the water spray device.

2 ) Start the transport tape under the screen.

3 ) Start the vibrating screen and notify the upper process to feed the mine after normal operation.

3. Should check during operation

1 ) Check whether the screen is loose during operation, whether the screen is worn, whether the spring, wire rope, screw rod and transmission belt are intact.

2 ) If the sieve surface is agglomerated, stop the ore supply and hit the bottom of the sieve in time to remove the agglomeration. If it is found that the screen is damaged, it should be repaired or replaced in time.

3 ) Always check if there is any noise in the bearing, and if the drive shaft has axial movement, if it is found, stop and repair it in time.

4 ) Check the lubrication of each part and whether the fixed parts are good, the temperature rise of the eccentric shaft, the motor and the reducer, if one of them exceeds 60 °C , should stop to check, and then drive after troubleshooting.

4. Parking sequence

1 ) After receiving the parking signal, notify the first process stop in time, wait for the next process to stop, all the sieve ore will enter the next process, and then stop the screening machine. After the next transportation tape is not mine, stop transporting the tape.

2 ) Stop the dust collector.
