Reasons for material deviation and slow material feeding on high-frequency vibration dewatering screen

High-frequency vibration dewatering screen is one of the commonly used equipment in industrial production. In order to meet the needs of dehydration and classification of fine-grained materials, and to 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, during operation, sometimes there will be problems of material deviation or slow material feeding, which will affect production efficiency and dehydration effect. This article will discuss the reasons why the material of the high-frequency vibration dewatering screen is deviated or the material is slow.

The reasons why the material does not move forward in the high-frequency vibration dewatering screen may be as follows:

1. Improper installation of the vibration motor: The vibration screen transports and screens the material through the vibration source body-the vibration motor to give the material a designed fixed direction and fixed size of exciting force. Therefore, if there is a problem with the installation angle of the vibration motor, poor material feeding may occur. In addition, long-term load work may cause some parts of the body to loosen, and will also change the angle of the vibration motor, resulting in material deviation and accumulation.

2. Insufficient excitation force of the vibration motor: The excitation force of the vibration motor required by the vibration screen needs to be precisely calculated based on the specific data such as the specific gravity of the material, the single processing volume, and the screening mesh number. During the long-term use of customers, the vibration motor's vibrating force may weaken. In addition, if the type of screening material is changed or the output is increased due to production needs, the vibrating dewatering screen may also have a slow material feeding problem due to inconsistent excitation force.

3. Failure to feed evenly as required: If the feeding is more or less, it is easy to cause unstable screening accuracy, and the material force deviation is large due to the amount of material, resulting in material deflection.

4. The shock-absorbing springs and other parts of the screen body are aging and loose: In addition to providing shock-absorbing effects, these parts also affect the vibrating force and the horizontal stability of the linear dewatering screen body. If a certain part has aging and other problems, the linear dewatering screen surface is uneven and the screen machine is unstable, causing the problem of material discharging direction deviation.

5. The center of gravity of the dewatering screen itself is unstable or the eccentric block of the motor is unbalanced: This situation may cause unstable flow of materials on the screen surface, thereby affecting the material conveying and dehydration effect.

6. Different materials and stiffness of shock-absorbing springs: Some manufacturers with prices lower than normal sales prices may cut corners on shock-absorbing springs and other components, resulting in a decrease in the overall stability of the dewatering screen and affecting the material conveying and dewatering effect.

7. Screen box deformation: Large, high-frequency dewatering screens need to withstand the gravity of large quantities of screened materials and the strong excitation force of the vibration motor. The screen frame may become fatigued or deformed after long-term vibration, weakening the vibration effect. If the screen box is not strong enough, it is easy to deform and damage, and then the material flow will be abnormal.

8. Blockage of screen pores: 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.

The high-efficiency high-frequency dewatering screen of Xingaonai Heavy Industry adopts linear vibration + electromagnetic vibration. Under the same conditions, all sorting indicators are better than other screen machines, with high screening efficiency and large processing capacity. It can quickly remove moisture from sand and gravel, improve product quality and output. At the same time, it also has a long service life and higher stability, and can adapt to various harsh working environments. So far, it has become an indispensable equipment in the sand and gravel production lines of many users with its significant advantages of high efficiency and durability.
