Circular vibrating screens will inevitably encounter some minor faults in daily production. If these faults are not resolved in time, it will easily bring a lot of trouble to your normal production. We often emphasize the need to do the daily maintenance and maintenance of the circular vibrating screen in order to be able to find the failures and safety hazards of the circular vibrating screen in time and minimize the economic loss of customers. The following are the common faults and solutions of circular vibrating screens.

1. Slow running and bearing heating
The bearing is damaged or badly installed, you need to replace the bearing or adjust the normal clearance of the bearing seal ring; the bearing part is lack of grease or unqualified grease, excessive oil filling, and you can adjust for different situations.
2. Abnormal sound
Loose fasteners, shaker gear damage, bearing damage, sieve plate damage, beam damage or cardan shaft damage, spring damage, except for loose fasteners that can be tightened, other parts need to be replaced.
3. Run obstacles
Inability to operate or the amplitude is too small: the main consideration is whether the motor is damaged, and the second is to check whether the control circuit components are damaged; check whether the screen surface has accumulated too much; check whether the shaker is malfunctioning, and whether the lubricating grease is agglomerated. The circular vibrating screen has an incorrect running trajectory, and the screen box vibrates abnormally: the reasons may be damage to the spring, damage to the side plate support, abnormal vibration exciters, and uneven entry into the screen, and it can be corrected appropriately for different situations.
4. Severe vibration
The gap between the screen and the fixed steel structure is too small, and the degree of freedom of the screen is not enough, just adjust the gap; the natural frequency is too close to the frequency of the screen, it is necessary to increase the weight and hardness of the structural parts; There is coal accumulation in the feed chute or coal accumulation in the discharge chute, which results in insufficient freedom of the sieve, clean the coal accumulation in time.
5. Poor screening quality
As the moisture in the sieve material increases or the fines increase, the inclination angle of the sieve box needs to be changed; the mesh is blocked to reduce the load on the sieve surface; The transmission belt is too loose. Adjust the method to tighten the screen and tighten the transmission belt. Or the particles on the sieve contain particles that are smaller than the size of the sieve. The sieve is clogged, the sieve is cleaned or the amplitude is increased; the incoming material is too much.
The above are the main points of the daily maintenance work of the circular vibrating screen. If you encounter similar failures in daily production, you can refer to the troubleshooting of the circular vibrating screen explained above, which can save you a lot of unnecessary trouble, maintenance time and costs.
