Screening effect and efficiency of the vibrating screen can affect the output and production efficiency of the whole production line. Here are some reasons that affect the screening effect and efficiency of vibrating screen.

Experiments show that adding surface-active material to water containing material can increase the activity and dispersibility of materials, and improve the screening condition. Besides, using the vibrating screen deck that is made up of non-hydrophilic materials also can improve the screening efficiency.

The soil is easy to knot and lock the mesh in the screening process. Clayey materials and viscous materials can only be screened with large mesh in some special cases. Wet screening is spraying water on the material that is moving along the vibrating screen deck, and pre-desliming before screening.

The particle characteristic mainly refers to the content of various grained materials that have a specific influence on the vibrating screening process. When the difficult screening material is much more than other fractions, the screening process is better. The particle characteristics also include the shape of particles. It is easier to screening for those particles who have close three-dimensional sizes, such as spheres and polyhedrons. In other conditions, it is more difficult to screening for those particles with large different sizes, such as slice, strip and weird shape.

There is no effect on the screening effect if all particles are the same density. However, if the density of coarse and fine particles are different, the situation is totally different. If the coarse-grained density is small, then fine-grained density is large. In contrast, coarse-grained density is larger and fine-grained density is small.

Movement type of vibrating screen deck is related to the looseness of the oversize material layer and the speed, direction and frequency of vibrating screen motion. In the vibrating screen, movement type of screen deck is divided into several kinds of forms: circular vibration, linear vibration and elliptical vibration. Xinhai has developed a series of vibrating screens with high screening quality, such as circular vibrating screen, auto centering vibrating screen, linear vibrating screen.

In general, the screen width directly determines the processing capacity of the vibrating screen. The wider the screen, the larger the processing capacity. The screen length determines the screening efficiency. The longer the screen, the higher the screening efficiency. When the screen length reaches a certain size, the screening efficiency will be rarely increased, or even no longer increases. And if you increase the screen length now, only the size and quality of screen are increased.

Screen slope has a great influence on the screen strength. The larger the screen slope, the smaller particle size, the smaller the screen slope, the larger particle size. In order to exclude oversize material easier, sometimes the screen deck should be installed obliquely. The larger slope, the faster the material layer moves on the screen deck, the greater the productivity. But the time that material stays on the screen deck is shortened, which decreases the screen-penetrating probability and reduces the screening efficiency.

The larger screen, the higher unit area screening efficiency and the higher screening efficiency. In general, the larger the mesh size, the higher porosity of the screen. When the mesh size is certain, the larger porosity of screen is more beneficial to the screening of vibrating screen. However, but the porosity of screen is often limited by screen strength and service life.

For certain screen and raw materials, the operating condition mainly refers to the quantity and mode of feeding. Continuous and even feeding is the best feeding method. In addition, please timely clean and maintain screen deck, which is also conducive to screening effect of the vibrating screen.

The effect of screen length on the screening efficiency of particles is studied under various single parameter conditions including frequency, amplitude, vibration angle, and screen inclination. The Discrete Element Method (DEM) has been used to simulate the screening process. A functional relationship between screening efficiency and screen length is established. It is shown that screening efficiency and screen length have a complicated exponential relationship. Relationships between them are profoundly discussed and conclusions are easily drawn: low values of the parameters do not benefit screening; screening efficiency generally increases with screen length; screening efficiency reaches a plateau when these parameters are in range frequently encountered in practical applications.

The vibrating screen is a kind of sieving equipment of international advanced level,developed by our company on the basis of carrying on the advantages of traditional screens and absorbing the outstanding technology from abroad.It is widely used for grading and screening materials in the following fields:minerals,quarry,building materials,water conservancy and hydropower,transportation,chemical industry, smelting and so on.

Motor through V-belt makes vibrator eccentric block to rotate at a high speed.Rotary eccentric block produces big centrifugal force,stimulates screen box to make round motion at some amplitude,materials on the inclined sifter receive impulse from the screen box and produce continuous casting movement,in the process of touching between materials and sifter granules that is less than sieve pore is through sieve and realizes grading.
