Liquids flow from the filter bag to the outside of the bag. The filter particles are trapped inside the bag. The working principle of the bag filter is pressure filtration.The bag filter system mainly consists of three parts: filter container, support net basket and filter bag.


Generally, PE/PP filter bag filter precision units are expressed in terms of how many "micrometers" (mu m), while the units of nylon filter and stainless steel filter filter are represented by the "eye".


"Eye" means per square inch (25.4 mm) 1 inch screen on the number of perforation, 50 mesh is on every square inch of perforation is 50, 500 mesh is 500, the higher the mesh, the more perforation;In addition to the perforation of the screen, it is used to indicate the particle size of the particle that can pass through the sieve. The higher the number, the smaller the particle size.


From the definition of "eye" can see above, the size of the aperture and the filter cloth woven with the diameter of the yarn, in be used actually, documentary silk, multifilament yarn and knitting methods also have a lot to do, at the same time, and use the speed of the centrifuge (centrifuge force), the performance of the filter material, temperature, etc all have much to do, so choose appropriate oneself condition and selection of the filter bag is a very complicated process.


At present, the diameter of the calculated diameter of equivalent volume particles is compared.It is expressed as mu m or mm.
