Influencing Factors of Efficiency of Vibrating Screens

Vibrating Screens sieve efficiency and efficiency can also affect the entire production line and production efficiency, ZK Corp for everyone to analyze the impact of screening efficiency factors.

First, the impact of the nature of raw materials into the screen.
1. Water content
Experiments show that sometimes the surface active substances added to the water content of materials can improve the activity and dispersion of materials to improve the screening conditions, cannot be made of water wetting the screen surface, but also improve the efficiency of the screen.
2. Mud content
Soil in the screening process is easy to knot group, easy to plug the sieve. Clay materials and viscous materials, only in some special circumstances with a larger screen surface screening sieve. Sieve rosary ore, you must use special measures, namely wet sieving. Wet sieving is like moving along the sieve surface of the material on the water, sieve before the pre-desliming, sifting raw materials for drying, with electric surface of the supermarket and sticky ore, can get good results.
3. Particle size characteristics
Particle size characteristics affecting the screening process mainly refers to the content of raw materials containing a variety of granular materials of particular significance to the screening process. Raw materials contained in the difficult to screen particles and hinder particles relative to other particle size is more favorable to the screening process. The particle size characteristics that influence the sieving process also include the shape of the particles.
4. The density characteristics
When all the particles in the material are of the same density, there is generally no effect on the sieving. However, when the material in the coarse, fine particles exist density difference, the situation is not the same. If the coarse grain density is small and the fine particle density is large, it is easy to sieve. On the contrary, coarse-grained density, small particle density, such as containing more coarse-grained gangue coal, screening is relatively difficult.

Second, the impact of sieve performance

1. Screen surface movement
The movement of the sieve surface is related to the looseness of the material layer on the screen and the speed, direction and frequency of the fine material relative to the sieve surface movement, and thus the stratification through the screening process have an impact. In the vibrating screen, the screen surface movement in the form of circular vibration, linear vibration and elliptical vibration of several. Which elliptical vibration movement in the form of higher screening quality.

2. Screen surface structure parameters
A. Screen surface width and length
In general, the width of the screen surface determines the handling capacity of the screen, the wider the screen surface, the greater the handling capacity; screen surface length determines the screening efficiency of the screen, the longer the screen surface, the higher the efficiency.
B. Screen surface inclination
The sieve surface inclination has the influence to the sieve intensity, the angle of inclination is big, the falling grain size reduces, the angle of inclination is small, the falling grain size increases.
C. The size, shape and perforation of the sieve
The larger the sieve, the higher the unit sieve area of the processing capacity of the higher screening efficiency. In general, the larger the mesh size, the higher the opening area of the screen surface.
