What should I do if the linear vibrating screen fails?

In the daily use of the linear vibrating screen, it is inevitable that some damage will not occur. Today we introduce the common faults and solutions of the linear vibrating screen.

The linear vibrating screen is driven by double vibration exciters. When the two vibration exciters are synchronized and rotated in opposite directions, the excitation force generated by the eccentric block cancels each other in the direction parallel to the motor axis, and in the direction perpendicular to the motor axis. Stacking is a resultant force, so the trajectory of the screen is a straight line. The two motor shafts have an inclination angle relative to the screen surface. Under the combined force of the exciting force and the material’s self-gravity, the materials are thrown up and jump forward on the screen surface for linear motion, so as to achieve the purpose of screening and grading materials. Can be used to realize automated operations in the assembly line. It has the characteristics of low energy consumption, high efficiency, simple structure, easy maintenance, and fully enclosed structure without dust spillage. The high screening mesh is 400 meshes, which can screen out 7 kinds of materials with different particle sizes.

1. The pipe beam is broken

If the wall of the pipe beam is too thin, it may cause breakage. At this time, the thick-walled pipe of the same model or the larger one should be used. But it should not be too large or thick, because this will increase the vibration quality of the sieve and cause many problems; the joints of each sieve plate of the dewatering and de-intermediation screen must have horizontal and vertical beading. If there is no longitudinal beading, water The pipe beam will leak from the gap between the screens and the pipe beam will easily break at the scouring point; the wider the screen, the easier the pipe beam will break. According to experience, when the screen width exceeds 3m, use dual channels.

2. The beam is broken

The beam fracture is mostly due to the long working time at the critical frequency, the loosening of a large number of high-strength bolts that fasten the side plates, and the serious deformation of the spring makes the left and right heights vary greatly. It is also possible that the weight error of the eccentric block is too large, causing damage to the structural parts. The beam is broken. At this time, the damaged structural parts and beams should be replaced, the bolts should be tightened, and the quality of the eccentric block should be adjusted.

3. The screen frame is broken

The screen frame is prone to fracture due to shaking. The best way to solve this problem is to thicken the side plate or add additional plates to the local area of ​​the side plate near the exciter to enhance the rigidity of the entire screen frame.

4. The discharge port is broken

Since vibrating screens are generally manufactured non-standard, the sizes required by customers are different. Some require the discharge port to be extended forward or downward. In this way, the discharge port will be relatively more likely to break. If it is the first design, the plate thickness or ribs can be strengthened. If it breaks accidentally, check the material quality. Also check whether the parameters of the vibrating screen are correct. Furthermore, during the feeding process, avoid excessive feeding of the vibrating screen at one time. The screen can be basically fully utilized. The excessive feeding amount not only affects the screening effect, but also the screened material cannot be discharged through the screen in time. Excessive weight backlog will also cause the break of the vibrating screen’s discharge port.

If the linear vibrating screen fails, you can refer to the above methods to solve it, but if your problem has not been solved, please contact the manufacturer for after-sales service, and ask professionals to repair it in time to avoid reducing your work efficiency.
