Vibrating screen common troubleshooting methods

Fault phenomenon

the reason

Method of exclusion

1. Unable to start or small amplitude
1) Motor damage
2) Damage to electrical components in the control circuit
3) Insufficient voltage
4) too much material on the screen surface
5) The vibrator has failed
6) The grease in the vibrator becomes thick and agglomerated
1) Replace the motor
2) Replace electrical components
3) Change the power supply
4) Clean the screen material
5) Overhaul the vibrator
6) Clean the vibrator and update the appropriate grease.

2. Material flow movement is abnormal


1) The horizontal level of the screen box is not correct
2) The support spring is too large or damaged
3) Damaged screen surface
4) Feeding material is extremely unbalanced
1) Adjust the height of the bracket
2) Adjusting the spring
3) Adjust the screen surface
4) Uniform operation, stable feeding

3. Vibrating sieve screening quality is not good


1) Screen hole blockage
2) The moisture content of the sieve material increases
3) Uneven feeding of the sieve machine
4) The layer on the sieve surface is too thick
5) The screen is not pulled tightly, the transmission belt is too loose
1) Uniform operation, stable feeding
2) Reduce the load on the vibrating screen and clean the screen surface
3) Change the screen box inclination
4) Adjusting the feeding of the sieve machine
5) Reduce the feeding of the sieve machine
6) Tensioning the screen and tightening the drive belt

4. The sieve machine rotates slowly during normal operation, and the bearing heats up.


1) Bearing lacks lubricating oil
2) Bearing blocking
3) Bearing oil is overfilled or improper oil is added
4) The bearing is damaged or poorly installed, the eccentric block on the round wheel is off, eccentric
1) Inject lubricant into the bearing
2) Clean the bearing, replace the seal, and check the labyrinth seal
3) Check the bearing lubricant
4) Replace the bearing, install the eccentric block, and adjust the round wheel
