Effetto della dimensione delle particelle del vaglio oscillante lineare sull'efficienza della vagliatura
The characteristics of the material have a great influence on the screening process of the vibrovaglio lineari, comprese le caratteristiche della dimensione delle particelle, contenuto di umidità, contenuto di impurità, forma del materiale e densità del materiale, which will affect the screening accuracy of the vibrovaglio lineari.
Primo, the effect of the particle size of the vibrovaglio lineari on the screening efficiency.The sieved material is easy to be sieved and difficult to sieved. The presence of impurities has a great influence on the sieving process. Since the easily separated materials easily pass through the sieve holes, the materials remaining on the surface of the sieve are rapidly reduced, thereby greatly reducing the interference with the materials that are difficult to sieve.
Secondo, the shape of the material also has a greater impact on the accuracy of the screen. If the shape of the material is irregular, it is difficult to ensure the accuracy of the material screening. Generalmente, irregular materials require multiple screening processes. Per esempio, sieving coarse materials from unqualified materials contained in the materials, and sieving fine materials. After several screenings, the screening accuracy can be controlled within a certain range.
Terzo, the way the material moves on the screen surface of the vibrovaglio lineari.The relative movement between the surface of the screen and the material is a necessary condition for screening. The movement can be divided into two types, one is the three-dimensional movement of the material on the surface of the screen, such as a linear vibrating screen, and the other is that the particles move mainly parallel to the screen. Due to the three-dimensional movement of the material on the screen surface, the material layer is loose, the separation speed increases the possibility of the material passing through the screen hole, and the screening efficiency and screening accuracy are greatly improved. The frequency and amplitude of the screen surface also have a great influence on the screening efficiency, which will affect the moving speed and the possibility of the material passing through the screen surface. In genere, materials with smaller particle sizes are suitable for small amplitude and high frequency vibration.
Il quarto, the effect of the moisture content of the material on the screening effect.In the actual production process, the water content determines the ease of material selection.If the water content is large, the material is usually dried and then sieved using a linear vibrating screen. Inoltre, when the same material is sieved with sieves with different sieve openings, the effect of moisture on the sieving efficiency is also different. The larger the mesh, the smaller the effect of moisture. Because the larger sieve holes can quickly sift out small water particles, the moisture of the material on the surface of the sieve is greatly reduced, and the effect of moisture on the sieving process is reduced. If the proportion of water in the material is large, the moisture content in the material reaches 80% or higher, or the material is displayed in the form of a slurry, it can basically be called filtration. It can be treated with ordinary vibrating screen or dehydrating screen.
