High-frequency vibrating dewatering screen is one of the commonly used equipment in industrial production, in order to not only meet the needs of dehydration and classification of fine-grained materials, but also achieve the purpose of large processing capacity, good dehydration effect and strong adaptability, it adopts the mechanical characteristics of high frequency and high vibration intensity, however, in the process of operation, sometimes there will be the problem of material deviation or slow material walking, which affects the production efficiency and dehydration effect. This article will be the reasons for the deviation of the material of the high-frequency vibrating dewatering screen or the slow material walking.
There may be several reasons why the high-frequency vibrating dewatering screen does not move forward:
1. Improper installation of the vibrating motor: the transportation and screening of the material by the vibrating screen is pushed by the vibrating source body-vibrating motor to the material with a designed fixed direction and fixed size of excitation force, so the installation angle of the vibrating motor is problematic, and there may be poor material transportation. In addition, long-term load work may lead to the loosening of some parts of the body, and will also change the angle of the vibrating motor, resulting in the phenomenon of material deviation and accumulation.
2. The excitation force of the vibrating motor is insufficient: the excitation force of the vibrating motor required by the vibrating screen needs to be accurately calculated according to the specific data of the specific data of the material, the single processing capacity, and the number of screening meshes. In the process of long-term use by customers, there will be a weakening of the vibrating sieve force of the vibrating motor, in addition, if the replacement of the type of screening material or the increase of output due to the production needs, it will also lead to the problem of slow material walking due to the inconsistency of the excitation force of the vibrating dewatering screen.
3. Failure to feed evenly as required: if the feeding time is more or less, it is easy to cause the instability of the screening accuracy, and the material stress deviation is large due to the amount of material, and the problem of material deviation occurs.
4. The damping spring and other parts of the screen body are aging and loose: in addition to providing shock absorption effect, these parts also affect the vibration screen force and the horizontal stability of the linear dewatering screen body.
5. The position of the center of gravity of the dewatering screen itself is unstable or the position of the eccentric block of the motor is unbalanced: this situation may lead to the unstable flow of materials on the screen surface, which will affect the dehydration effect of material transportation.
6. The material of the shock absorbing spring is not.
1. Different stiffness: Some manufacturers that are lower than normal sales may cut corners on components such as shock absorber springs, resulting in a decrease in the overall stability of the dewatering screen and affecting the dehydration effect of material transportation.
7. Deformation of the screen box: The large-scale, high-frequency dewatering screen needs to withstand the gravity of a large number of screening materials and the strong excitation force of the vibrating motor, and the screen frame may be fatigued or deformed after bearing long-term vibration, weakening the vibration effect, and if the strength of the screen box is not enough, it is easy to deform and damage, and then the phenomenon of abnormal material flow occurs.
8. Screen pores are blocked: After long-term use, slag will accumulate on the surface of the screen and block the screen holes. As a result, the material cannot flow normally on the screen surface.
