There are three main causes:
1. The Impurities in the filter particles clog the mesh, as there are many particles close to the size of the mesh opening;
2. spherical particles or materials with multiple contact points to the mesh, in simple terms, the reason for blocking the mesh is that the contact area is increased;
3. the material is fibrous, and there are many flake particles;
Besides, since the sieved particles are mostly irregular, the cause of the blockage is also varied.
When the particle size of the material is fine, the mud content is large, and the sieving particle size is small, the blockage of the stainless steel wire mesh by moisture will play a decisive role. When the moisture in the material is more than 5%, if the material is dried unconditionally, should choose the mesh surface and hole size targeted . When the moisture is greater than 8%, wet screening should be used. For materials with a large number of flaky particles, it is necessary to change the crushing method of the materials and the particle size matching of different crushing methods and processes, and select the appropriate solution based on the causes and characteristics.
