Factors affecting the vibration frequency of the dewatering screen
2021-06-10
Due to different materials, the frequency of each vibrating dewatering screen is different, some run fast, some run slow. What factors affect the vibration frequency of the dewatering screen? How to adjust? This article will share some experiences with you.
The inconsistent frequency of the excitation force of the dewatering screen will reduce the dewatering effect. If the excitation force is too small, the dehydration effect is not good, and the production efficiency will be reduced. Excessive vibrating force, although the dehydration effect is improved, will damage the vibrating screen itself. For example, in the sieve plate, if the excitation force is too large, the sieve plate will make a large amount of action, which will cause the sieve plate to break and ultimately cause economic losses.
Factors affect the vibration frequency of the dewatering screen
1. Control of screening area
The width of the screen surface is the main factor that determines the vibration frequency of the dewatering screen. To ensure the screening effect of the material, the material on the screen surface needs to have an appropriate thickness. When the thickness of the material is constant, the passing capacity of the material mainly depends on the width of the vibrating screen, so the wider the screen surface, the greater the production capacity. However, the width of the vibrating screen should not be too large. If the width is too large, it is difficult to ensure uniform feeding during use.
2. Determination of the inclination of the screen surface
The frequency of vibration of the dewatering screen is often used for the dewatering, desliming, and dewatering of coal. Because the dewatering screen with linear motion is generally installed horizontally, the inclination angle is zero. At this time, the movement of the material mainly depends on the projectile force that is at a certain angle to the horizontal when the screen surface moves. If a straight screen is used for classification, the inclination angle of the screen is about 5-7 degrees.
3. Control of vibration frequency
Generally, the vibration frequency of the screen is usually between 750~1500 times/min. According to the long-term production experience of the dewatering screen manufacturer of Longzhong Heavy Industry, the frequency should be between 850~1000. The installation engineer will adjust it to the user during the installation process. Vibration frequency.
4. Use multiple feeding methods
Using multiple feeds is equivalent to increasing the screen width and reducing the thickness of the material layer on the surface. It is helpful for fine particles to quickly touch the screen, reduce the transportation distance of coarse particles, and improve work efficiency. In addition, it is necessary to strengthen the maintenance of the screen machine, clean the screen surface and repair it, and replace the damaged screen surface to ensure that the equipment is in good condition.
The above four factors are the factors and solutions that affect the speed and efficiency of the vibrating screen. If your equipment has malfunctions that you don’t know about during operation, please feel free to contact us and we will give you a professional solution.
