The methods of loading mesh screen of the linear sieve

　　The way of loading the linear sieve: single-layer net, sub-mother net, single-layer bouncing ball, sub-mesh net with bouncing ball;

　　1) Single-layer net: It is suitable for products with large aperture, easy to be sieved with low bulk density; for example: granular compound fertilizer with aperture of 4mm and 2mm;

　　2) Sub-master net: It is suitable for materials with easy to be sieved but with high bulk density, such as 60-mesh iron powder;

　　3) Single-layer bouncing ball: It is suitable for materials that are not well sieved, have moderate bulk density, and have a mesh number of 150 or more high; for example: aluminum powder: 20 mesh, 40 mesh, 60 mesh;

　　4) The sub-mesh with the bouncing ball: more suitable to the material with difficult screening, bulk density, mesh number more then 60 mesh; for example: quartz sand, 60 mesh, 100 mesh, 150 mesh, etc.;

　　5) A sieve machine can use a variety of meshing methods. For example, the screening material is quartz sand, and the mesh number is 10 mesh, 20 mesh, 40 mesh, and 120 mesh. At this time, 10 mesh can be used for single mesh. 20 mesh, 40 mesh can use a single layer with a bouncing ball, 120 mesh can use a parent network with a bouncing ball;
