Vibrating screen is widely used in many fields, in numerous sand production line is mainly used for screening application. In addition, also for coal preparation, ore dressing, building materials, electricity and chemical industries for product classification. Accordingly, vibrating screen operation quality to a great extent, affected the whole process of project. So, let’s to talk about common fault vibrating screen solution, and how daily maintenance.
1. The vibrating screen cannot be started or the amplitude is small. At this point we need to check the motor, line components for damage, voltage is not enough; in addition, is not too much material on the sieve surface of the vibrating screen.
2. Vibration is abnormal. At this point, we need to check whether the connecting bolt is loosened and tighten in time; or whether the bearing seat, the spring and the screen supporting the foot spring have problems; in addition, there may be reasons for the imbalance of the feeding material, etc. .
3. The results of screening are poor. This is most likely caused by improper operation, such as uneven feeding, high material humidity, loose belt, abnormal screen blockage.
4. The vibrating screen runs slowly and the bearing heats up. This may be due to the lack of grease in the bearing and the quality of the grease chosen will also have a large effect.
5. Noise is high. At this time, it is necessary to check whether the bearing is damaged or not, and in addition, there is a possibility that the beam is broken and the spring is damaged.
6. The joint is cracked or the joint is cracked. When the vibration exciter is installed, the corresponding eccentric wheel’s vertical line does not coincide with its natural heavy vertical line due to the torque of the transmission shaft, which causes the eccentric wheel to rotate asynchronously, so that the amplitude of each part of the vibrating screen is inconsistent; or the eccentric wheel counterweight is not Suitably, the amplitude of the vibrating screen will also be out of balance. Then, the vibrating screen has a phenomenon that the joint portion is cracked or the joint weld is cracked.
