Sieve and sieve would affect the shape of the screen

Screen size in 25mm above, generally with the punching or drilling hole plate, most of the circular, rhombic arrangement. 25mm the following can be woven mesh, woven mesh is a square hole. 25mm can be used to punching sieve, sieve, sieve knitted or woven mesh, should prevent the screen strip sliding, mesh deformation. For 1mm the following Mining vibrating screen(include desliming, dehydration, de medium) using slit plate below 0.5mm can use slotted sieve plate (with screw wear strips rings or welding) or nylon mesh. Whether sieve or mesh, itself must be tightened, and the screen box fastening, this is very important. Can prolong the sieve plate, a screen box life, improve Dewatering screen efficiency, but also can reduce the noise.
The sieve plate above 50mm, often made of steel or light rail made. Especially the fixed screen using the old rail is more suitable. The claviform screen bars are made of the wedge, the narrow width, convenient material through.The circular aperture, the diameter of the circle aperture to indicate size, can guarantee the size are smaller than the screen size, the undersize basic does not contain more than the mesh size, but the diagonal One's natural genius is surpassing. shape is 1.414 times the length of that, some data by maximum particle hole, equivalent to 1.23 times the maximum particle size through a circular the. Rectangular mesh with short edges of the rectangular aperture size as the name, in this case, the size of more than sieve size, especially along the long edge of the flatparticles through the sieve mesh. There are some irregular mesh, such as braided mesh. Probability sieve often greater than the separation size and screen projection calculation. In any case, screening granularity is a measure of the size of standard products.
