Ultra fine wood powder machine first can be some small pieces of wood, sawdust, peanut shell, small branches were made after the destruction of fineness in 30-300 mesh fineness. But on some first touch wood powder machine industry users, products processing equipment maybe coincidence mesh meaning is not very clear. Technical personnel today win there on the mechanical wood powder machine product fineness unit mesh with us to explain the significance.
Number is the number of holes, which is the number of holes per square inch. The greater the number, the smaller the aperture. In general, mesh aperture (micron number) * =15000. For example, the aperture of the 400 mesh screen is about 38 microns; the aperture of the 500 intention screen is about 30 microns. Because of the opening rate of doubt, that is because the mesh with the thickness of the wire is not the same, not the same as the national standard is not the same, the American Standard, British and Japanese code three, which is near the United Kingdom and the United States, Japan greatly different.
Thus, it can be seen that the size of the mesh resolution screen aperture size. For example, the fineness of the processed products of the wood flour mill reaches 30-300 meshes. The size of the screen aperture determines the maximum particle size of the screened powder D max. So, we can see that the 400 intention of polishing powder have maybe very fine, for example, as long as 1-2 microns, are perhaps 10 microns, 20 microns. Because the screen aperture is about 38 microns. We produce 400 D50 with a polishing powder of 20 microns. Notice that the ruler is 50 microns. Refers to the number of orders per square inch empty eye screen, which is 50 orders per square inch on the hole is 50, 500 is 500, the higher the number, the more. In addition to show the screen hole, it can pass the screen to indicate that the particle size, the higher the number, the smaller the particle size.
