Maintenance Notes for Circular Vibrating Screen

1. Always keep the circular vibrating screen working in a clean and sanitary environment.

2. The bearing on both ends of the motor should be lubricated with anti- high temperature lubricating grease, in the first month, please lubricate once a week .

3. Check flange bolts on both sides of motor, the bolts which fix the mesh and the support connecting bolt shouldn’t have loose phenomenon.

4. The circular vibrating screen should be maintained every half year.

A. clean the vibrator and add grease for all lubricating points.

B. check the abrasion condition of screen mesh, if any damage , please maintain and replace timely.

5. The circular vibrating screen should be maintained and repaired every year. 

A. Open the motor terminal box ,check the insulation between the wires and clean the dust.

B. Add grease on all lubricating points.

C. check each part of the circular vibrating screen and abrasion condition of screen mesh, if any damage please maintain and replace timely.

E. After finishing all the work, a trial run is also required.

How to Prolong the Lifespan of Vibration Motor

1. Make sure the wiring and insulation work of vibration motor is well done in order to prevent the lack of phase and short circuit .

2. Anchor bolt reinforcement work should be done frequently, take necessary prevention measures, such as using a double nut fastening to ensure vibration motor base and the floor contact well.

3. Attach great importance to the cover sealing of vibration motor, the dust inside the protection cover should be cleaned up frequently.

4. Strengthen the daily maintenance of vibration motor, remove the dust on the motor surface frequently, and reduce the impact on the vibrating motor due to the poor heat dissipation in order to make it work in a good condition.

 

5. Please pay attention to the symmetry when adjusting the vibration block, the gravity connection center line of vibration block on both sides should be parallel to axis.

6. Check whether there is crack on motor appearance, all fastening screws and parts are complete and the fixed situation of the motor are in good condition or not.

7. Check whether the ventilation and bearing lubrication condition of vibration motor is normal or not.

8. Pull out the motor axis and check if rotor can rotate freely and whether there is noise during rotation.

9. Check whether the grounding device is reliable or not.

Troubleshooting for Gyratory Screen

As one of our main product, gyratory screen has been supplied to many plants all over the world and also enjoys a good reputation because of its superior design and quality. Gyratory screen is widely applicable to chemical, food processing, refractory materials, building materials, activated carbon, food, PVC powder and other fine materials.
However, during the operation, we may meet some problems, here PK Machinery will introduce the breakdown reason and method in detail.

Breakdown	Reason	Solution
V-belt heating up	V-belt looseness Through of belt is broken or the surface is rough	Loose the bolt which fastens the motor, adjust the distance between motor and belt pulley Check and repair the belt pulley
Bearing heating up	The grease is excessive or shortage or the quality is bad Bearing is broken Main shaft bends or the inertial force is not balanced The bearing cup is not compatible with other parts Belt is too tight Overload working for a long time	Change the grease Change bearing Correct the main shaft Change the part which coordinate with the bearing Adjust the tightness of the V-belt Reduce the feeding rate
There is no force for motor	Two phase electricity Circle short for the winding Overload working for a long time	Power on the lost phase electricity to ensure it runs under 3 phases Inspect the motor Keep the screen working under the rated load
Fail to start the motor	Low voltage Electrical wiring is too thin Fuse is broken	Start the screen once electricity is normal Change the electrical wiring Change a proper fuse
Violent or wiggly vibration	The rotation shaft bends Bearing is broken	Replace or correct the shaft Replace the bearing
The unqualified size material mixed in the finished material	Screen mesh is broken Screen cover or seal bar is loose	Renew the screen mesh Press the cover and seal bar
Capacity declining	The moisture is too high, block the mesh The opening size is not suitable Rotation speed is low or the V-belt is loose Feeding rate is low The rubber ball is worn out	Reduce the moisture of material Renew the screen mesh Check the belt pulley and the tightness of belt Increase the feeding rate Renew the feeding rate

The technical precision screening enough do vibrating screen

 1. Screen mesh plug (to increase the anti clogging device).

2. Cast material moisture into the vibrating screen is too large (viscosity, after appropriate input vibration after drying sieve).

3. The vibration sieve surface feeding uneven (add the material divider)

4. The vibration sieve surface material layer is too thick (increasing material divider, control the feeding amount)

5. Often to sieve sieve load and vibration reducing vibration cleaning gently

6. Change the screen box angle

7. Mediation of the vibration sieve feeding quantity

8. Tension screen, narrow transmission leather

Analysis of field application of starch vibrating screen extension

As the name suggests, vibrating screen is used for the separation,classification and sorting of starch. And the main equipment is rotary vibration screen.

 

The advantages are as follows:

1.The mesh number of material with screened is small that can achieve micro powder sieving. There is dust cover in the top layer so that can prevent the dust, protect environment and improve the working environment of workers.

2.Outlet of the machine can be adjusted the direction within the scope of 360 degrees in a horizontal plane based on the axis in the center of the screening equipment.

3.Screen machine has low energy consumption and can save resources.
