Multilayer vibrating screens and high-frequency screens are commonly used in the field of industrial screening. Their technical parameters have a crucial impact on the screening effect and equipment performance. The following will introduce these key technical parameters in detail.
I. Technical parameters of multi-layer vibrating screen
1. Amplitude: Amplitude refers to the vibration amplitude of the screen box when the vibrating screen is working. The amplitude of the multi-layer vibrating screen is usually large to screen more effectively. Generally speaking, the size of the amplitude directly affects the screening efficiency. Too large an amplitude will cause the material to jump too high and reduce the screening efficiency; too small an amplitude may prevent the material from being fully dispersed, which also affects the screening effect.
2. Vibration frequency: The vibration frequency is the number of times the vibrating screen vibrates per unit time. The vibration frequency of the multi-layer vibrating screen is moderate to ensure a balance between the residence time of the material on the screen and the pass rate. Too high a vibration frequency may cause the material to pass through the screen too quickly, reducing the screening accuracy; while too low a vibration frequency may cause the material to accumulate on the screen, affecting the screening efficiency.
3. Screen surface inclination: The screen surface inclination refers to the angle between the screen and the horizontal plane. The screen surface inclination of the multi-layer vibrating screen is usually adjusted according to the characteristics of the material and the screening requirements. The appropriate screen surface inclination angle helps to improve screening efficiency and screening accuracy, while reducing the clogging of materials on the screen.
II. High frequency screen technical parameters
1. Amplitude and vibration frequency: Compared with multi-layer vibrating screens, high-frequency screens have smaller amplitudes but higher vibration frequencies. This design enables high-frequency screens to have higher screening efficiency and accuracy when processing fine-grained materials. High-frequency vibration helps prevent material clogging on the screen and ensures that the material can be evenly dispersed on the screen.
2. Screen structure and materials: High-frequency screens usually use fine screen structures and wear-resistant materials to adapt to the working environment of high-speed vibration. The aperture and wire diameter of the screen are customized according to the particle size and screening requirements of the material to ensure the best screening effect and service life.
In summary, the technical parameters of multi-layer vibrating screens and high-frequency screens are of great significance to the screening effect and equipment performance. When choosing a suitable vibrating screen model, it is necessary to comprehensively consider factors such as the characteristics of the material, screening requirements and working environment. At the same time, regular maintenance and maintenance of the equipment are also the key to ensuring the screening effect and extending the service life of the equipment.
In practical applications, multi-layer vibrating screens and high-frequency screens have their own advantages, which are suitable for different screening needs and material characteristics. Multi-layer vibrating screens are suitable for processing materials with larger particle sizes that require multi-stage screening, while high-frequency screens are more suitable for accurate screening of fine-grained materials. Therefore, when choosing a vibrating screen, comprehensive consideration should be given to actual needs to ensure the best screening effect and economic benefits.
