Test sieve sieve box is a device mounted on a standard test sieve machine for round test sieves manufacturers, with a diameter of 200mm and 300mm two types of commonly used is 200mm, but some users have special requirements also have 75mm of. Mesh sieve box by 8 mesh to 500 mesh are, the larger the mesh, the smaller the hole, and therefore, according to the size of the mesh, there are perforated plates and two of wire braid. The number is small perforated plate, is a large number of wire braid. Also useful mm sieve frame number to represent the size of test sieves price, this is just another way of saying, between both can be converted. Standard test sieves are YZU vertical vibration motor as vibration source machine, vibration motor driven by the upper vibration plate vibration, and then through the vibration plate vibration transmission to be placed on the upper plate Φ200 screen frame, and then the screen frame is necessary to detect the mesh The screen surface is smaller than the mesh material particles to lower screening test sieve sieve box model, so the layers of screening, so that the material within each test sieve, leaving only the same size, to achieve separation of different particle size and to determine the composition of this material, the material Φ200 type sieve box can play a very effective filtering, classification, screening purposes.
