When considering the appropriate sieve, it's important to think about not only the size of the openings but also the type of frame you select. Sieve frames serve as a stable base for securely attaching and maintaining the mesh while containing the sample material during shaking. Round test sieves are designed with a flange that allows them to be stacked together, creating a multisieve configuration ideal for utilization in a sieve shaker.

Frame diameter - The diameter of the frame plays a crucial role in matching the sieve size to the volume of the sample. If a small frame is used to contain a large sample, the separation process will be suboptimal. Particles may not find openings properly, leading to in complete size fractions. A common rule of thumb is to verify that there are no more than one or two material layers left on the sieve following the separation procedure.

Choosing a larger sieve offers the advantage of using a more representative sample, thereby improving the precision of fraction separation. On the other hand, smaller sieve frames offer better control when dealing with fine powders and are more manageable for thorough particle retrieval during cleaning. Certain testing protocols suggest that sieves should have a minimum of five complete openings, which places constraints on the maximum size of mesh apertures. The chart provided delineates frame diameters and crucial measurements for ASTM E11 and ISO 3310 test sieves.

When deciding on the suitable sieve size for your particle analysis, it's advisable to consider the dimensions of the particles you intend to analyze. For example, if you are dealing with particles that have a maximum size of 1 inch, then test sieves with a diameter of up to 8 inches would be well-suited for precise testing. In cases where your sieve analysis aligns with this scenario, you can determine the specific sieves within this size range that align with industry standards.

Conversely, if the particles have an average size greater than 1 inch, employing 12-inch sieves may yield more accurate results. The slightly increased depth of these sieves offers additional space for larger particles to efficiently pass through the mesh openings, enhancing the effectiveness of the analysis.

Incorporating backing cloth prolongs the primary sieve's lifespan and counteracts the impacts of frequent use and overloading. The coarser No. 30 (600μm) wire mesh is placed ben eath the finer No. 70 (212μm) or finer primary mesh to reinforce wet-wash sieves.
