Common problems and solutions for linear Vibrating Screen

1.The production processing capacity of the linear vibrating screen is lower than the theoretical calculation value. We can simply adjust the position of the eccentric wheel of the linear vibrating screen on the vibrating screen, adjust the feeding mode of the vibrating screen, and adjust the vibrating screen. The amplitude and the inclination of the device are used to solve the problem. Different applications have different technical requirements for the processing capacity and screening efficiency of the vibrating screen. Therefore, the above methods need to be flexibly applied according to specific conditions.

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

Affected by various factors, the linear vibrating screen often fails to meet the original design requirements after being put into production. Specifically, the amplitude is too low, and the low amplitude will reduce the entire processing capacity of the linear vibrating screen; in the opposite case, if the amplitude of the linear vibrating screen is too high, then the bearing will be The service life of the seat, bearing and vibrating screen sill has a certain impact. Therefore, under normal circumstances, the user can directly change the quality of the eccentric according to the situation of the use of the linear vibrating screen, or use a spring of different stiffness to adjust the amplitude of the linear vibrating screen. Adapt to the needs of production.

3. When the linear vibrating screen is used in the coal industry, the screen surface of the vibrating screen has a fault phenomenon that the coal is not good, and the linear vibrating screen is prone to large swing and vibration at the moment of opening and stopping.

In the process of actual use of the linear vibrating screen in the coal industry, if there is a phenomenon that the front part of the linear vibrating screen does not go out of the coal, the technician can appropriately adjust the position of the eccentric wheel forward; if it is the rear part of the linear vibrating screen There is a phenomenon that the coal does not go out, the user can also adjust the position of the eccentric wheel slightly later; if the middle part of the linear vibrating screen does not take coal, this means that the quality of the eccentric is too light, the amplitude If the user's requirements are not met, it is necessary to properly increase the quality of the eccentric to solve this problem. In another case, if it is a linear vibrating screen for grading or dewatering, if the position of the flushing pipe on the screen surface is improperly matched, the screen surface of the linear vibrating screen may not appear to be coal. Therefore, the user can appropriately adjust the position of the flushing pipe and solve the problem by speeding up the running speed of the material on the screen surface. However, this method is only suitable for screening or dewatering of materials of 0-3mm. In the above method, if it is impossible to solve the problem of the linear vibrating screen in production, the user can appropriately change the linear vibration by fully ensuring the screening efficiency of the linear vibrating screen and fully ensuring the processing amount. The amplitude of the sieve or the inclination angle solves the problem that the linear vibrating screen is not good for coal.

4. The bearing housing of the linear vibrating screen is easy to be cracked, the bearing is easy to be damaged by heat, and the bottom beam of the sieve is easy to be welded or broken.

The problem of bearing failure is often caused by the fact that the mass of the eccentric of the linear vibrating screen is too large, resulting in an increase in the exciting force and an increase in the amplitude of the vibrating screen. In the event of this failure, the user can often handle it by reducing the mass of the eccentric or by replacing the spring with a higher stiffness. At the same time, under the premise of ensuring the strength of the shaft, the user can also handle by changing the bearing of different models or changing the strength of the bearing housing. At the same time, the necessary reinforcement of the bottom beam of the linear vibrating screen can also extend the service life of the linear vibrating screen.
