High-frequency vibration dehydration screen is one of the commonly used equipment in industrial production. In order to adapt to the needs of dehydration and grading of fine-grained materials, and to achieve the purpose of large processing volume, good dehydration effect and strong adaptability, it adopts mechanical characteristics of high frequency and high vibration strength. However, during operation, sometimes the material is off or slow to move, which affects the production efficiency and dehydration effect. This article will discuss the reasons why high-frequency vibration dehydration screen materials run off or slow material flow.
There may be the following reasons why materials do not move forward in high-frequency vibration dehydration screen:
1. Improper installation of the vibration motor: The vibration screen of the material transport screen is pushed by the vibration source body – the vibration motor to give the material a fixed direction and a fixed size vibration force. Therefore, if there is a problem with the installation angle of the vibration motor, the material may be poorly conveyed. In addition, long-term loading work may cause some parts of the body to loosen, which will also change the angle of the vibrating motor, and cause materials to run off and accumulate.
2. The vibration force of the vibration motor is insufficient: the vibration force required for the vibration screen needs to be accurately calculated based on the specific gravity of the material, the single processing quantity, and the number of screening mesh. During the long-term use of the customer, the vibration screen force of the vibrating motor will weaken. In addition, if the types of screened materials are replaced or the output is increased due to production needs, the vibration dehydration screen will also cause the problem of slow material removal due to inconsistent vibration force.
3. Failure to feed the material evenly as required: If the material is often more or less frequently when feeding, it is easy to cause unstable screening accuracy, and the material is subject to a large deviation in the pressure due to the amount of material, resulting in a problem of material skew.
4. The shock absorbing springs and other components of the screen body are aging and loose: In addition to providing shock absorption effects, these components also affect the vibration screen force and the stable level of the linear dehydration screen body. If a certain component has problems such as aging, it will cause problems such as discharging due to uneven screen surfaces of the linear dehydration screen, which will cause problems with the discharging direction.
5. The center of gravity position of the dehydration screen itself is unstable or the eccentric block position of the motor is unbalanced: This situation may cause unstable flow of materials on the screen surface, which will affect the dehydration effect of material transport.
6. Different materials and stiffness of shock absorbing springs: Some manufacturers whose prices are lower than the normal sales price may cut corners on components such as shock absorbing springs, resulting in a decrease in overall stability of the dehydration screen and affecting the dehydration effect of material transportation.
7. Screen box deformation: Large and high-frequency dehydration screens need to withstand the gravity of large batches of screening materials and the strong excitation force of the vibration motor. The screen box may experience fatigue or deformation after long-term vibration, which weakens the vibration effect. If the screen box is not strong enough, it is easy to cause deformation and damage, and then abnormal material flow occurs.
8. Clogged screen holes: After long-term use, dregs will accumulate on the surface of the screen, blocking the screen holes. This causes the material to not flow normally on the screen surface.
