subject: Factors That Influence The Screening Efficiency [print this page] The grain size of the screened materials is of decisive influence on the screening process line. Materials containing easier screen tablets are easy to be screened, the productivity of the sieve will increase rapidly. To maintain productivity in certain circumstances, you can get a higher screening efficiency.
The materials contained in the surface water screening process. Surface water enables fine-grained materials bonded into a group with each other, and attached to the large particles; the viscous material will mesh blocked. These reasons, when screening the same water content of the same materials, make water impacts the screening efficiency differently. The larger the mesh is, the smaller the water impact has. Therefore, when moisture content of materials is higher, it will seriously affect the screening process; at this moment it may be considered appropriate to increase the sieve method to improve the screening efficiency. However, the specific impact of the water for screening certain materials, according to test results to determine. Screening sticky ore, must take effective measures to strengthen the screening process, wet sieving or screening before the pre-tin off the mud.
Particle shape of the screening, also have some impact, such as round particles is relatively easy through the square and round hole. Broken product is mostly angular, easy to empty through the rectangle; strip, plate, sheet materials is difficult through the square hole, but more easily through the rectangular hole.
Operating conditions of the screening machine
Screening process should ensure uniform and continuous feed, so that the material thickness along the entire width of the sieve dissatisfaction thin layer, we take full use of the screen surface, they can obtain higher productivity and screening efficiency. Prompt cleaning and maintenance of the screen surface are also important conditions of the screening process.
