Several Factors Affecting the Working Efficiency of Circular Vibrating Screens

How to improve the working efficiency of circular vibrating screen has always been the concern of vibrating screen users. Zhongxin Heavy Industry professional and technical personnel summed up the following reasons, users can use vibrating screen can be concerned about, through these reasons, we can maximize the vibration Screening efficiency.


vibrating screen

The technical and economic indicators of the screening process are screening efficiency and productivity. The former is the quality index, the latter is the number of indicators. There is a certain relationship between them, but also with many other factors, these factors determine the screening results. Factors that affect the screening process can be divided into three categories:
1.Screened material physical properties
Including the material itself particle size composition, humidity, clay content and particle shape. When the material content of large particles, the sieve productivity is also large. When the humidity of the material is larger, the screening efficiency will generally be reduced. However, the larger the size of the sieve, the smaller the impact of moisture, so for moisture-containing larger wet materials, in order to improve the screening process, generally can be used to increase the sieve approach, or the use of wet screening. Material with mud content (when the mud content is greater than 8%) should be used wet screening.
2.Screening the impact of production conditions
When the sieve load is large, screening efficiency is low. To a great extent the rate of sieve peace depends on the size of the sieve and the total screening efficiency; the larger the sieve size, the lower the screening efficiency required, the higher the productivity. Feed uniformity is of great significance to the screening process.
The inclination of the sieve should be appropriate, generally determined by the test. And then the amplitude and vibration of the sieve, which is related to the structural properties of the sieve, in a certain range, increase the vibration can improve the screening index.
3. Screen surface properties and the impact of structural parameters
Vibrating screen is to make particles and screen for vertical movement, so screening efficiency, production capacity. The relative movement of particles and screen surface is mainly parallel movement of bar screen, flat shaker, cylinder screen, the screening efficiency and productivity are low.
For a given material, screen productivity and screen efficiency depend on the mesh size. Productivity depends on the screen width, screen width and high productivity. Screening efficiency depends on the screen surface length, screen surface length screening efficiency. The general aspect ratio of 2.
The larger the effective screen area, the higher the unit area productivity and screen efficiency of the screen surface. The larger the sieve size, the greater the productivity of the unit screen surface, the higher the screening efficiency.
