The relationship between the size of the test sieve frame and the weight of the sample
2023-05-29
When using a test sieve for particle size distribution testing, we recommend that the sample weight be around 25-100g, depending on materials with different specific gravity, at this time, an accurate weighing scale or balance is needed to weigh and record the weight. What we mean by mesh size is a term that describes the diameter or mesh of a sieve. In this guide, mesh size refers to the diameter of the sieve. Now, as mentioned above, sieves with diameters of 400mm, 300mm, 200mm or 750mm can be used. The accuracy of sieve analysis results depends on selecting the correct sieve size. This is because the sieve diameter ultimately determines whether or not your sample material covers more than 50% of the sieving media. When more than 50% is covered, the moving space of the sample particles will be restricted, making it difficult to find the opening of the mesh, or even clog the sieve media. Typically, test sieves up to 200mm in diameter are well suited for accurate testing of these particles. If your sieve analysis operation is similar, you can use your industry standards to determine which sieves in that sieve size range are best for you.
