Vibration dehydration equipment is common dehydration equipment. It has a wide range of uses, not only in industries such as sand making and beneficiation, but also in industries such as engineering mud dewatering, industrial wastewater treatment, and environmental protection engineering mud purification. There will be many problems that customers cannot solve during use. This article will explain to you the common failures and solutions of dewatering screens.

1. The production and processing capacity of the dewatering vibrating linear screen is lower than the designed theoretical calculation value

The production capacity of the dewatering screen is lower than the calculated value of the design theory, we can simply adjust the position of the eccentric wheel of the dewatering screen on the vibrating screen. You can adjust the feeding method of the vibrating screen, or adjust the amplitude of the vibrating screen and the inclination angle of the equipment to solve the problem. Different use occasions have different technical requirements for the processing capacity and screening efficiency of the vibrating screen. Therefore, the users of the above method need to be flexibly applied according to the specific situation.

2. The amplitude of the dewatering screen is lower than the parameters required by the design

Affected by various factors, after the dewatering screen is put into production and use, the amplitude of the dewatering screen is often not up to the original design requirements. The specific performance is that the amplitude is too low, and if the amplitude is low, the entire processing capacity of the dewatering screen will be reduced. On the contrary, if the amplitude of the dewatering screen is too high, it will affect the service life of the bearing seat, bearing, and bottom beam of the vibrating screen. Therefore, under normal circumstances, users can directly change the quality of the eccentric wheel according to the use of the dewatering screen or choose springs of different stiffness to adjust the amplitude of the dewatering screen to meet the needs of production.

3. The dewatering screen is used in the coal industry.

The screen surface of the vibrating screen has a problem of bad coal removal, and at the moment of starting and stopping, the dewatering screen is prone to large swings and vibrations, which affects the service life of the spring.

When this phenomenon occurs, the technician can properly adjust the position of the eccentric wheel forward. If it is said that there is no coal phenomenon in the back section of the dewatering screen, the user can also adjust the position of the eccentric wheel slightly. If there is no coal in the middle section of the dewatering screen, it means that the mass of the eccentric is too light.

4. The bearing seat of the dewatering screen is easy to vibrate, the bearing is easy to be damaged by heating, and the bottom beam of the screen is easy to be welded or broken. These problems often occur because the mass of the eccentric wheel of the dewatering screen is too large, which leads to the increase of the exciting force and the amplitude of the vibrating screen.

In the event of this failure, the user can deal with it by reducing the mass of the eccentric or replacing the spring with greater stiffness. On the premise of ensuring the strength of the shaft, the user can change the bearing of a different model or change the strength of the bearing seat to deal with it. At the same time, strengthening the bottom beam of the dewatering screen can also extend the service life of the dewatering screen.
