What happened in the process of usingVibration screen：
Unable to start or small amplitude
1.  Vibration motor is damaged
     Change vibration motor
2. The control circuit of the electrical components is damaged
    Chenge electrical components
3. Insufficient voltage
    Change the power purveyance
4. Screen surface materials piled up too much
    Cleanup screen surface material
5. Vibrator fails
    Maintenance vibrator
6. Grease thickened and caking in the vibratior
Cleaning vibrators, updateing and adding the appropriate grease
The movement of material flows anomalies
 1. Horizontal level of the vibration screen box is not right
    Adjusting bracket height 
2. Support spring stiffness is too large or damage
     Adjusting spring
3. Screen surface is damaged
    Adjust the screen surface
4. The uneven feed
     Even operation, stable feeding
 Screen quality is poor
 1. Mesh plug
     Light screening machine load and clear the screen surface
2. The sieve material moisture increases
    Changing the angle of the screen box
3. Sifter feeding inequality
    Adjust the screening machine feed
4. Screen surface material layer is too thick
   Reduced screening machine feed
5. Screen is not tight, drive belt is too loose
    Taut screen mesh, tighten belt
During normal operation sifter rotation slows down, bearing heating
1. Bearing lack  lubrication
   Injected into the  lubricant
2. Bearing block
    Cleaning bearings, replace the seals, check seals
3. Bearing grease is too much or join inappropriate oil
   Check bearing lubricant   
4. Bearing is damaged or poor installation, the eccentric is round off and different sizes, sealing is jammed
    Replacement of bearings, installation eccentric, adjust wheel adjustment
Other faults
1. Bearing is damaged
    Change bearing
2. The screen is not tight, screen surface fixed not firm
     Tensioned screen
3. Bearing mounting bolts loose
     Tighten the bolts
4. Spring is damaged
   Replace the spring
